I've never faced this problem before but after I've recently renewed my PC (a new MoBo and CPU) I'm now randomly getting this kernel message after booting the PC: [ 4684.693288] irq 18: nobody cared (try booting with the "irqpoll" option) [ 4684.693294] Pid: 0, comm: swapper Tainted: P 2.6.37-ic #1 [ 4684.693296] Call Trace: [ 4684.693303] [<c129ebd9>] ? printk+0x18/0x1a [ 4684.693309] [<c1066637>] __report_bad_irq.clone.2+0x27/0x90 [ 4684.693314] [<c10667ef>] note_interrupt+0x14f/0x190 [ 4684.693320] [<c101cc72>] ? ack_apic_level+0x62/0x1b0 [ 4684.693323] [<c1068354>] ? move_native_irq+0x14/0x50 [ 4684.693328] [<c10672fb>] handle_fasteoi_irq+0xab/0xd0 [ 4684.693332] [<c1067250>] ? handle_fasteoi_irq+0x0/0xd0 [ 4684.693334] <IRQ> [<c1004e24>] ? do_IRQ+0x44/0xc0 [ 4684.693340] [<c1003229>] ? common_interrupt+0x29/0x30 [ 4684.693344] [<c1003229>] ? common_interrupt+0x29/0x30 [ 4684.693348] [<c103007b>] ? scheduler_tick+0x18b/0x220 [ 4684.693353] [<c117553f>] ? intel_idle+0xaf/0x100 [ 4684.693357] [<c1221c6e>] ? cpuidle_idle_call+0x6e/0xf0 [ 4684.693360] [<c10016e6>] ? cpu_idle+0x46/0x80 [ 4684.693365] [<c129127b>] ? rest_init+0x7b/0x80 [ 4684.693369] [<c13986e1>] ? start_kernel+0x26e/0x274 [ 4684.693373] [<c13981b9>] ? unknown_bootoption+0x0/0x1a3 [ 4684.693377] [<c139808e>] ? i386_start_kernel+0x8e/0x90 [ 4684.693379] handlers: [ 4684.693380] [<f89b4c20>] (e100_intr+0x0/0xd0 [e100]) [ 4684.693397] Disabling IRQ #18 The Internet and even kernel bugzilla are rife with reports like this one and almost all of them are left unanswered or unresolved (for instance see kernel bugzilla reports 15307 and 17672). Can anyone shed light on this problem? How one can debug/understand/eliminate it? Is it safe to use irqpoll boot option? Best wishes, Artem ^ permalink raw reply [flat|nested] 4+ messages in thread

Have a look into /proc/interrupts to see which drivers are registered for irq 18 (e100 in your case), then search in the output of "lspci -v" for any _other_ devices that use irq 18. It's also possible that one of the drivers is buggy and mistakenly said "this interrupt is not from my device", or, in theory, that the BIOS is buggy and has mislabeled some device's interrupt. According to Google, there are other reports of this message with the e100 driver. Does your network work? If not, does irqpoll help?

You could try to blacklist the i2c-i801 module (add the line blacklist i2c-i801 to any existing or a new file in /etc/modprobe.d/) and then rebooting. > I will try to reboot with irqpoll a bit later however before I try it I'd > be very grateful to know what exactly this option does/if it affects > performance/stability/etc and why it's not used/enabled by default. The irqpoll option is used for machines with broken interrupt routing; when an interrupt arrives, the kernel tries the handler for all other interrupt lines, too, and it does the same checks in every timer interrupt (in case that some interrupt did not arrive at all). This lowers performance, and is useful only if some device would _not_ work without it. Your e100 works, so don't bother. Regards, Clemens ^ permalink raw reply [flat|nested] 4+ messages in thread
