Adding "nosmp apm=force noapic api=off pci=noacpi" after a reboot of system appeared to work on first inspection. Some time after reboot there are more interrupts and a write to /var/log/messages. Hard on a disk to say the least. What we see is: Jun 25 09:31:47 engr01 kernel: spurious APIC interrupt on CPU#0, should never happen. Jun 25 09:32:55 engr01 kernel: spurious APIC interrupt on CPU#0, should never happen. Jun 25 09:34:37 engr01 kernel: spurious APIC interrupt on CPU#0, should never happen.

There does not seem to be much on the net that offers any advice or ??? Need to solve this problem before I have another disk to swap out. It is unique to a single core processor installation, as we have looked for this same activity on several boxes with multi core processor and it doesn't happen. Larry Linder
