Comment 42 for bug 66900

I experienced the same problem (only installed ubuntu Edgy Eft a day ago)
prj@gordon:~$ grep "APIC error" /var/log/* | wc -l
335551

Tried updating to latest known BIOS version (1.04c AMI) for Fujitsu-Siemens Amilo 7640W didn't help. Neither did adding boot options noapic (then sound device died and Gnome wouldn't come up) nor nolapic (same thing) or trying to set various i8042 boot options. What seems to have cured it is setting the boot option irqpoll (add it in /boot/group/menu.lst on line beginning with kernel). Not trying to reopen the issue, just adding a comment with workaround that might help others with same problem. This discussion was first hit on google when I searched for the problem. I spent lots of time reading forum posts all over the net about this. Maybe there is no general solution, and it's not really a BIOS problem (at least not only, though it might be for some) and all those "solutions" are workarounds for linux kernel not to alert about faulty hardware. Well, those are my 5 cents. Thanks for good work on making Ubuntu.
