That\u0027s not a terribly unusual\n\u003e \u003e configuration and nothing should get confused in the system.\n\u003e\n\u003e But it _does_ get confused, really.\n\n Something certainly gets confused, but so far I am not sure which bit\nexactly it is, are you?\n\n\u003e \u003e Barring the unlikely possibility of the 8259A actually being wired to\n\u003e \u003e INTIN2 of the I/O APIC I can see two possible explanations:\n\u003e \u003e\n\u003e \u003e 1. The 8259A interrupt actually escapes to the CPU somehow and is handled\n\u003e \u003e as an ExtINTA interrupt. This would make the code in check_timer()\n\u003e \u003e decide it has found a working configuration, while actually it has been\n\u003e \u003e fooled.\n[...]\n\u003e Here you go:\n\u003e\n\u003e [ 0.108006] ..TIMER: vector\u003d0x30 apic1\u003d0 pin1\u003d2 apic2\u003d-1 pin2\u003d-1\n\u003e [ 0.108006] ..MP-BIOS bug: 8254 timer not connected to IO-APIC\n\u003e [ 0.108006] ...trying to set up timer (IRQ0) through the 8259A ... \u003c3\u003e\n\u003e [ 0.108006] .....

In this case I suspect the case #1 quoted above happens, that is\nthe 8259A manages to deliver its interrupt somehow. Note at this stage it\nis meant to be in the AEOI mode, so it can happily resubmit the interrupt\nindefinitely with no additional handling as long as it receives INTA\ncycles.\n\nCan you please try the patch below on top of \"x86: I/O APIC: timer\nthrough 8259A second-chance\" to see whether my hypothesis is true? It\nmodifies the through-8259A setup path so that the APIC input gets masked,\nbut the 8259A has the timer interrupt still enabled. Let me know how the\ntimer interrupt is routed in this case.\n\nBisected-by: \"Rafael J. Wysocki\" \u003crjw@sisk.pl\u003e\nTested-by: \"Rafael J.

The\nlater variant is seen as a code symbol and recorded in the kallsyms data.\n\nOn fix would be to move the exception table a little bit and get some\nspace between that two areas.\n\n[1]: http://buildd.debian.org/fetch.cgi?pkg\u003dlinux-2.6\u0026arch\u003dalpha\u0026ver\u003d2.6.25-5\u0026stamp\u003d1213919009\u0026file\u003dlog\u0026as\u003draw\n\nCc: maximilian attems \u003cmax@stro.at\u003e\nCc: Richard Henderson \u003crth@twiddle.net\u003e\nCc: Ivan Kokshaysky \u003cink@jurassic.park.msu.ru\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "fc26361ef0fbcad0406475fc6006fa4f09e60dce", "tree": "26c8b01954156e5fae34acb281093cc815e56edc", "parents": [ "7fc7228c0be9007f0e6a32c8a8ae340ea6246056" ], "author": { "name": "David Howells", "email": "dhowells@redhat.com", "time": "Fri Jul 04 09:59:47 2008 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Jul 04 10:40:07 2008 -0700" }, "message": "mn10300: provide __ucmpdi2() for MN10300\n\nProvide __ucmpdi2() for MN10300 so that allmodconfig can be built.\n\nSigned-off-by: David Howells \u003cdhowells@redhat.com\u003e\nCc: Adrian Bunk \u003cbunk@stusta.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "7fc7228c0be9007f0e6a32c8a8ae340ea6246056", "tree": "b2686dfab2e927886070cdf0d110b19ab6b6ed4b", "parents": [ "292d73551d0aa19526c3417e791c529b49ebadf3" ], "author": { "name": "David Howells", "email": "dhowells@redhat.com", "time": "Fri Jul 04 09:59:46 2008 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Jul 04 10:40:07 2008 -0700" }, "message": "mn10300: export certain arch symbols required to build allmodconfig\n\nExport kernel_thread() and empty_zero_page so that allmodconfig can be\nbuilt for MN10300.\n\nSigned-off-by: David Howells \u003cdhowells@redhat.com\u003e\nCc: Adrian Bunk \u003cbunk@stusta.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "d8355aca23863be659ec5b7e0393cfbfa91ec221", "tree": "cd6b96eef8ac85df2519dd0f64c5f2a458b22b3f", "parents": [ "27df66a406a171308b138bd84938cb735392e15c" ], "author": { "name": "Jeremy Fitzhardinge", "email": "jeremy@goop.org", "time": "Thu Jul 03 22:10:18 2008 -0700" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Fri Jul 04 11:31:20 2008 +0200" }, "message": "xen: fix address truncation in pte mfn\u003c-\u003epfn conversion\n\nWhen converting the page number in a pte/pmd/pud/pgd between\nmachine and pseudo-physical addresses, the converted result was\nbeing truncated at 32-bits.

_cpu_up, the panic happens when calling\n__raw_notifier_call_chain at the second time. Kernel doesn\u0027t panic when\ncalling it at the first time. If just say because of nr_cpu_ids, that\u0027s\nnot right.\n\nBy checking the source code, I found that function do_boot_cpu is the culprit.\nConsider below call chain:\n _cpu_up\u003d\u003e__cpu_up\u003d\u003esmp_ops.cpu_up\u003d\u003enative_cpu_up\u003d\u003edo_boot_cpu.\n\nSo do_boot_cpu is called in the end. In do_boot_cpu, if\nboot_error\u003d\u003dtrue, cpu_clear(cpu, cpu_possible_map) is executed. So later\non, when _cpu_up calls __raw_notifier_call_chain at the second time to\nreport CPU_UP_CANCELED, because this cpu is already cleared from\ncpu_possible_map, get_cpu_sysdev returns NULL.\n\nMany resources are related to cpu_possible_map, so it\u0027s better not to\nchange it.\n\nBelow patch against 2.6.26-rc7 fixes it by removing the bit clearing

Thus early calls to native_sched_clock() would skip\nthe TSC and use jiffies instead.\n\nAfter the commit above, tsc_32.c uses a \"tsc_disabled\" variable\nwhich defaults to 0, meaning that the TSC is Ok to use. Early calls\nto native_sched_clock() now erroneously try to use the TSC on\n!cpu_has_tsc processors, leading to invalid opcode exceptions.\n\nMy proposed fix is to initialise tsc_disabled to a \"soft disabled\"\nstate distinct from the hard disabled state set up by the \"notsc\"\nkernel option. This fixes the native_sched_clock() problem. It also\nallows tsc_init() to be simplified: instead of setting tsc_disabled \u003d 1\non every error return, we just set tsc_disabled \u003d 0 once when all\nchecks have succeeded.\n\nI\u0027ve verified that this lets my 486 boot again.

As it is, the callers have to do extra work to handle the\n limit case gracefully. ]\n\nReported-by: Bron Gondwana \u003cbrong@fastmail.fm\u003e\nCc: Nick Piggin \u003cnpiggin@suse.de\u003e\nCc: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nCc: Andi Kleen \u003candi@firstfloor.org\u003e\nCc: Al Viro \u003cviro@ZenIV.linux.org.uk\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n\n (which didn\u0027t have this problem), and since\nmost users that do the carethis was very hard to trigger, but\n" }, { "commit": "c8988f968240069aeae16d8cf9f59096a085eb27", "tree": "5d75d8b6014353caf5ad9db2d189cd6427c80488", "parents": [ "10acaf0c8a481c1ea9ba9d550a292595d8279ee1", "732a675a6303156d1a197dc780b0712bd4b49d46" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Jun 16 11:52:43 2008 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Jun 16 11:52:43 2008 -0700" }, "message": "Merge branch \u0027release\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/aegl/linux-2.6\n\n* \u0027release\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/aegl/linux-2.6:\n [IA64] Fix CONFIG_IA64_SGI_UV build error\n [IA64] Update check_sal_cache_flush to use platform_send_ipi()\n [IA64] perfmon: fix async exit bug\n" }, { "commit": "10acaf0c8a481c1ea9ba9d550a292595d8279ee1", "tree": "11442de1365284c42f52a6a7a39375c9786bc55a", "parents": [ "649cf0ff4b998e3082c6d9d8673eaab71f3de656", "313348db0bff8911b1219e6338342d0527072741" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Jun 16 10:24:01 2008 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Jun 16 10:24:01 2008 -0700" }, "message": "Merge branch \u0027merge\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/paulus/powerpc\n\n* \u0027merge\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/paulus/powerpc: (21 commits)\n [POWERPC] Turn on ATA_SFF so we get SATA_SVW back in defconfigs\n [POWERPC] Remove ppc32\u0027s export of console_drivers\n [POWERPC] Fix -Os kernel builds with newer gcc versions\n [POWERPC] Fix bootwrapper builds with newer gcc versions\n [POWERPC] Build fix for drivers/macintosh/mediabay.c\n [POWERPC] Fix warning in pseries/eeh_driver.c\n [POWERPC] Add missing of_node_put in drivers/macintosh/therm_adt746x.c\n [POWERPC] Add missing of_node_put in drivers/macintosh/smu.c\n [POWERPC] Add missing of_node_put in pseries/nvram.c\n [POWERPC] Fix return value check logic in debugfs virq_mapping setup\n [POWERPC] Fix rmb to order cacheable vs. noncacheable\n powerpc/spufs: fix missed stop-and-signal event\n powerpc/spufs: synchronize interaction between spu exception handling and time slicing\n powerpc/spufs: remove class_0_dsisr from spu exception handling\n powerpc/spufs: wait for stable spu status in spu_stopped()\n [POWERPC] bootwrapper: add simpleImage* to list of boot targets\n [POWERPC] 83xx: MPC837xRDB\u0027s VSC7385 ethernet switch isn\u0027t on the MDIO bus\n [POWERPC] Updated Freescale PPC defconfigs\n [POWERPC] 8610: Update defconfig for MPC8610 HPCD\n [POWERPC] 85xx: MPC8548CDS - Fix size of PCIe IO space\n ...\n" }, { "commit": "626a16c16e13e4afaba382bfc0354a3555f5231c", "tree": "7a0a0c1f8e19b18c98757a076a4a03f294b75d10", "parents": [ "e53d6a152793a38aa334d6f7a4850642ae45cedc", "dab8c6deaf1d654d09c3de8bd4c286d424df255a" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Jun 16 10:22:31 2008 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Jun 16 10:22:31 2008 -0700" }, "message": "Merge branch \u0027upstream\u0027 of git://ftp.linux-mips.org/pub/scm/upstream-linus\n\n* \u0027upstream\u0027 of git://ftp.linux-mips.org/pub/scm/upstream-linus:\n [MIPS] Au1200: MMC resource size off by one\n [MIPS] TANBAC: Update defconfig\n [MIPS] Vr41xx: Initialize PCI io_map_base\n [MIPS] Malta: Always compile MTD platform device registration code.\n [MIPS] Malta: Fix build errors for 64-bit kernels\n [MIPS] Lasat: sysctl fixup\n [MIPS] Fix buggy use of kmap_coherent.\n [MIPS] Lasat: bring back from the dead\n [MIPS] vpe_id is required for VSMP and SMTC builds\n [MIPS] Export smp_call_function and smp_call_function_single.\n [MIPS] Bring the SWARM defconfig up to date\n [MIPS] Sibyte: Build RTC support as an object\n [MIPS] Fix the fix for divide by zero error in build_{clear,copy}_page\n [MIPS] Fix build for PNX platforms.\n [MIPS] Add RM200 with R5000 CPU to known ARC machines\n [MIPS] Better load address for big endian SNI RM\n [MIPS] SB1250: Initialize io_map_base\n [MIPS] Alchemy: Add au1500 reserved interrupt\n [MIPS] Export empty_zero_page for sake of the ext4 module.\n" } ], "next": "b052beb0432616aa4dac2b167e7809feae993991" }
