Hi I experienced such problems for months now, both on a AMD Athlon with nv5200(running proprietary drivers) and on a laptop with a centrino and a radeon 9600M(os drivers).
It used to happen under whatever kind of load (and to shot it down: I don't run compiz). Since beginning the problem was 100% "fixed" on the laptop passing noacpi nolapic parameters to kernel(both feisty and gusty). On the desktop I tried many different things until know but nothing wasn't enough (it used to freeze also without any X server running :D) After a bit of lkml reading I came to this: http://lkml.org/lkml/2007/8/21/435 [he is experiencing both mouse-only-freezes and *total*-hard-freezes :D] On both machines I'm running gusty now and I solved completely the problem by launching ASAP after login: sudo /etc/init.d/powernowd stop I've read that in many threads is asked to debug the crash :), but actually there is nothing I can do in my case: no way to get into the pc, no ssh, no ping, no nothing... (an already opened ssh session from a remote client to the freezing machine also freezes at the same time:) ) Hope to hear soon about ideas on how to fix this and how I may help, Thanks!
