I have had multiple IBM x306 servers loose interrupts. Eventually the
timer will get a few interrupts, but it can stay at the same spot for a
long time.
If I reboot, and then add append=noapic in lilo and reboot again I never
get a problem in the future.
One of the boxes I have has a third NIC and if I use noapic the machine
cannot boot. Is there something besides noapic I should try.
Is there any other information you would like?
