From: Signed-off-by: Darren Hart <[email protected]> All IRQs are migrated away from a CPU that is being offlined so the following messages suggest a problem when the system is behaving as designed:
IRQ 262 affinity broken off cpu 1 IRQ 17 affinity broken off cpu 0 IRQ 18 affinity broken off cpu 0 IRQ 19 affinity broken off cpu 0 IRQ 256 affinity broken off cpu 0 IRQ 261 affinity broken off cpu 0 IRQ 262 affinity broken off cpu 0 Don't print these messages when the CPU is not online.
