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] [] ? printk+0x18/0x1a [ 4684.693309] [] __report_bad_irq.clone.2+0x27/0x90 [ 4684.693314] [] note_interrupt+0x14f/0x190 [ 4684.693320] [] ? ack_apic_level+0x62/0x1b0 [ 4684.693323] [] ? move_native_irq+0x14/0x50 [ 4684.693328] [] handle_fasteoi_irq+0xab/0xd0 [ 4684.693332] [] ? handle_fasteoi_irq+0x0/0xd0 [ 4684.693334] [] ? do_IRQ+0x44/0xc0 [ 4684.693340] [] ? common_interrupt+0x29/0x30 [ 4684.693344] [] ? common_interrupt+0x29/0x30 [ 4684.693348] [] ? scheduler_tick+0x18b/0x220 [ 4684.693353] [] ? intel_idle+0xaf/0x100 [ 4684.693357] [] ? cpuidle_idle_call+0x6e/0xf0 [ 4684.693360] [] ? cpu_idle+0x46/0x80 [ 4684.693365] [] ? rest_init+0x7b/0x80 [ 4684.693369] [] ? start_kernel+0x26e/0x274 [ 4684.693373] [] ? unknown_bootoption+0x0/0x1a3 [ 4684.693377] [] ? i386_start_kernel+0x8e/0x90 [ 4684.693379] handlers: [ 4684.693380] [] (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
