Comment 73 for bug 585765

All, please note from the earlier posts.... florianr, myself, and others confirmed that the freezing we were seeing could still happen without X and the desktop running, and on very different video hardware. If your bug seems to be graphics related, you should probably report it separately.

I can confirm that I'm still seeing freezes under the latest lucid 2.6.32-23-generic and 2.6.32-23-preempt.

Further testing shows that if I boot with kernel parameters "noapic nolapic" then the freezing does not happen. I'm currently writing this while playing 720p video, ripping a DVD in Handbrake, recording an HD video in mythtv, commercial flagging a program, running virtualbox (busy doing a virus scan) and playing audio in amarok. While the system is pausing occasionally under the CPU/disk/memory load.... no freeze. A torture test that would be sure to freeze in a few seconds if I ran without "noapic nolapic". Further, if I boot with kernel parameter "noacpi" I still have freezes.... it has no effect on it's own. Again, this is a regression from karmic where I could run without "noapic nolapic".
