Hi everyone!
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)

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
