Though that check wants to be\nbackported to stable as well, which will require to fix all known\nproblematic platforms and probably some more yet not known ones as\nwell. Lots of churn.\n\nA way simpler solution is to allocate a slightly larger bitmap and\navoid the whole churn w/o breaking anything.

Level type\ninterrupts come back once enable_irq() re-enables the interrupt line.\n\nI assume that the interrupt in question is level triggered because it is\nshared and above the legacy irqs 0-15:\n\n\t17: 12 IO-APIC-fasteoi eth1, eth0\n\nLooking into the IO_APIC code, the resend via send_IPI_self() happens\nunconditionally. So the resend is done for level and edge interrupts.\nThis makes the problem more mysterious.\n\nThe code in question lib8390.c does\n\n\tdisable_irq();\n\tfiddle_with_the_network_card_hardware()\n\tenable_irq();\n\nThe fiddle_with_the_network_card_hardware() might cause interrupts,\nwhich are cleared in the same code path again,\n\nMarcin found that when he disables the irq line on the hardware level\n(removing the delayed disable) the card is kept alive.\n\nSo the difference is that we can get a resend on enable_irq, when an\ninterrupt happens during the time, where we are in the disabled region.\n\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "e317c8ccaaf900abf39cc3240e4dc5ba82a3cc67", "tree": "327b25cecd21d97097b1249fe73a5c9ff2a6bcc6", "parents": [ "b7696ee3c050a76a6cebccdbadfc93896b336e44" ], "author": { "name": "Frederik Deweerdt", "email": "deweerdt@free.fr", "time": "Fri Oct 06 18:58:24 2006 +0000" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Fri Oct 06 12:11:08 2006 -0700" }, "message": "[PATCH] ixp4xxdefconfig arm fixes\n\nWith the following patch, the ixp4xxdefconfig builds correctly.
