The occasional APIC error is fine (its logging a hardware event - probably something that caused enough noise to lose a message and retry it). The APIC bus is designed to stand these occasional errorsI'm curious... is there any way to determine what is causing these? On a UP athlon I have:
cw:tty5@charon(cw)$ uname -r ; uptime && grep ERR /proc/interrupts 2.4.17-rc2 02:09:50 up 4 days, 5:18, 10 users, load average: 0.00, 0.00, 0.00 ERR: 5216

which equates several per minute at times... no funny hardware, not running X11, and I don't remembering seeing these a while ago on this same mainboard (but I never really looked either, so that might not be true).
They are spurious IRQ 7, just message is printed only once during kernel lifetime... I have about three spurious IRQ 7 per each 1000 interrupts delivered to CPU. It is on A7V (Via KT133).
Best regards,

Any idea _why_ these occur though? It seems some mainboards produce a plethora of these whilst others never produce these...
