And when\nit does it hits the longjmp code and assumes the context of the oopsing CPU.\nThe machine gets very confused when it has 10 CPUs all with the same stack,\nall thinking they have the same CPU id. I get even more confused trying\nto debug it.\n\nThe patch below adds crash_shutdown_cpu and uses it to specify which cpu is\nin the protected region. Since it can only be -1 or the oopsing CPU, we don\u0027t\nneed to use memory barriers since it is only valid on the local CPU - no other\nCPU will ever see a value that matches it\u0027s local CPU id.\n\nEventually we should switch the order and marshall all CPUs before doing the\ncrash_shutdown_handles[] calls, but that is a bigger fix.\n\nSigned-off-by: Anton Blanchard \u003canton@samba.org\u003e\nSigned-off-by: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\n" }, { "commit": "426b6cb478e60352a463a0d1ec75c1c9fab30b13", "tree": "994b3a2dfa42d8c1bc976ed984a56cc52f910414", "parents": [ "ce47c1c45b2b17ad07af82c775f27cc5196080f8" ], "author": { "name": "Maxim Uvarov", "email": "muvarov@gmail.com", "time": "Tue May 11 05:41:08 2010 +0000" }, "committer": { "name": "Benjamin Herrenschmidt", "email": "benh@kernel.crashing.org", "time": "Fri May 21 17:31:09 2010 +1000" }, "message": "powerpc/crashdump: Do not fail on NULL pointer dereferencing\n\nSigned-off-by: Maxim Uvarov \u003cmuvarov@gmail.com\u003e\nSigned-off-by: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\n" }, { "commit": "ce47c1c45b2b17ad07af82c775f27cc5196080f8", "tree": "abdc0181553256e5fb230b8b27c1782f6f7e9a41", "parents": [ "5b339bdf164d8aee394609768f7e2e4415b0252a" ], "author": { "name": "Anton Blanchard", "email": "anton@samba.org", "time": "Mon May 10 15:38:56 2010 +0000" }, "committer": { "name": "Benjamin Herrenschmidt", "email": "benh@kernel.crashing.org", "time": "Fri May 21 17:31:09 2010 +1000" }, "message": "powerpc/eeh: Fix oops when probing in early boot\n\nIf we take an EEH error early enough, we oops:\n\nCall Trace:\n[c000000010483770] [c000000000013ee4] .show_stack+0xd8/0x218 (unreliable)\n[c000000010483850] [c000000000658940] .dump_stack+0x28/0x3c\n[c0000000104838d0] [c000000000057a68] .eeh_dn_check_failure+0x2b8/0x304\n[c000000010483990] [c0000000000259c8] .rtas_read_config+0x120/0x168\n[c000000010483a40] [c000000000025af4] .rtas_pci_read_config+0xe4/0x124\n[c000000010483af0] [c00000000037af18] .pci_bus_read_config_word+0xac/0x104\n[c000000010483bc0] [c0000000008fec98] .pcibios_allocate_resources+0x7c/0x220\n[c000000010483c90] [c0000000008feed8] .pcibios_resource_survey+0x9c/0x418\n[c000000010483d80] [c0000000008fea10] .pcibios_init+0xbc/0xf4\n[c000000010483e20] [c000000000009844] .do_one_initcall+0x98/0x1d8\n[c000000010483ed0] [c0000000008f0560] .kernel_init+0x228/0x2e8\n[c000000010483f90] [c000000000031a08] .kernel_thread+0x54/0x70\nEEH: Detected PCI bus error on device \u003cnull\u003e\nEEH: This PCI device has failed 1 times in the last hour:\nEEH: location\u003dU78A5.001.WIH8464-P1 driver\u003d pci addr\u003d0001:00:01.0\nEEH: of node\u003d/pci@800000020000209/usb@1\nEEH: PCI device/vendor: 00351033\nEEH: PCI cmd/status register: 12100146\n\nUnable to handle kernel paging request for data at address 0x00000468\nOops: Kernel access of bad area, sig: 11 [#1]\n....\nNIP [c000000000057610] .rtas_set_slot_reset+0x38/0x10c\nLR [c000000000058724] .eeh_reset_device+0x5c/0x124\nCall Trace:\n[c00000000bc6bd00] [c00000000005a0e0] .pcibios_remove_pci_devices+0x7c/0xb0 (unreliable)\n[c00000000bc6bd90] [c000000000058724] .eeh_reset_device+0x5c/0x124\n[c00000000bc6be40] [c0000000000589c0] .handle_eeh_events+0x1d4/0x39c\n[c00000000bc6bf00] [c000000000059124] .eeh_event_handler+0xf0/0x188\n[c00000000bc6bf90] [c000000000031a08] .kernel_thread+0x54/0x70\n\nWe called rtas_set_slot_reset while scanning the bus and before the pci_dn\nto pcidev mapping has been created.
