On my HP 2510p I get the following in dmesg during near the end of most resumes from suspend to RAM: irq 19: nobody cared (try booting with the "irqpoll" option) Pid: 0, comm: swapper Not tainted 2.6.28-rc7 #67 Call Trace: <IRQ> [<ffffffffa00ee9e1>] ? ohci_irq_handler+0x60/0x7e9 [ohci1394] [<ffffffff8026aa4d>] __report_bad_irq+0x38/0x87 [<ffffffff8026abaa>] note_interrupt+0x10e/0x174 [<ffffffff8026b262>] handle_fasteoi_irq+0xa7/0xd1 [<ffffffff8020eb87>] do_IRQ+0x73/0xe4 [<ffffffff8020c626>] ret_from_intr+0x0/0xa <EOI> [<ffffffffa0012606>] ? acpi_idle_enter_bm+0x26b/0x2b2 [processor] [<ffffffffa00125fc>] ? acpi_idle_enter_bm+0x261/0x2b2 [processor] [<ffffffff8024f30f>] ? notifier_call_chain+0x33/0x5b [<ffffffff803b9c64>] ? cpuidle_idle_call+0x8c/0xc4 [<ffffffff8020b312>] ? cpu_idle+0x4a/0x9a [<ffffffff8042c5c8>] ? rest_init+0x5c/0x5e handlers: [<ffffffffa00ee981>] (ohci_irq_handler+0x0/0x7e9 [ohci1394]) Disabling IRQ #19 There also seems to be an interrupt storm during suspend/resume when this happens: 19: 99968 33 IO-APIC-fasteoi ohci1394 This patch gets rid of both issues and makes the resume as a whole significantly faster. Signed-off-by: Frans Pop <elendil@planet.nl> As was pointed out in http://lkml.org/lkml/2008/12/6/127, this does not fix the cause of the interrupt storm. However, since the source of the interrupts could not be determined yet, we make the system at least more usable with this change. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de> |
