Comment 26 for bug 544548

Confirmed that the kernel parameter noacpi works around the problem. I hammered the system for hours this afternoon and NO failures (lost interrupt etc), when it would fail after about 15 minutes on average (1 minute to 30 minutes usually, mainly towards the 1 minute end).

However, the system seems a bit sluggish, but nothing that can be measured. (may be imagined)

USB also working OK, but webcam still on the blink, (another problem perhaps) where the webcam is identified as USB 1.1 only instead of USB 2. (happens on reboot 9 times out of 10)

Is the lost interrupt problem a buggy bios, as has been reported, or is this a problem in the kernel as some (possibly uninformed?) people have reported?
