Hi I have the same issue with Feisty (7.04) wih kernel 2.6.20 and all updates installed.
System freezes to a white screen a few minutes after launch of Firefox (also up-to-date). The only recovery option is a hard reset. I have not looked at logs to see what happened in the kernel. Disabling powernowd (sudo chmod -x /etc/init.d/powernowd) did nothing to help - the problem is still there. I am running an elitegroup ECS RS-482 Motherboard with built in ATI 200 Graphics card and AMD64 3500 proc. System is currently unusable (but is rock-steady under Windows XP - runs for weeks not requiring a reboot). Would love to dump Windows, but need a stable Ubuntu system. I am considering other options - (Gentoo did not seem to have this problem) Please keep this bug open. And anything else I can do on my side to get to the bottom of this and get the issue resolved.
