Question showing my ignorance of what acpi is. If pci=noacpi works or does not work, what clues is that giving me?
I didn't respond earlier because we've reached my level of ignorance too.
ACPI is the successor/combination of plug& play, advanced power management, et al...
If you have disabled ACPI and it did not make a difference, I would say the clue it's giving you is ACPI is not causing the error.
APIC, on the other hand, has to do with interrupt timing. Do you see any options in your BIOS for enabling/disabling/changing APIC's slices or timing?
Are you overclocking your RAM or CPU[s]?
Specifying apci=off in grub seems to have worked. Now I've booted with pci=noacpi, and so far it seems to be working. I'll let it run overnight with the X screensaver on to see if it cares to lock up. Then I'll try the nolapic and noapic options. Then I'll figure out what to try next.
I looked in the BIOS but did not see any options for fine tuning timing or slices. I'll look again next time I reboot. How should I manipulate slices or timing if I find that capability? And no, I'm not overclocking, at least not intentionally :).
Thanks for the questions. Please keep them coming.
