** Description changed: Frequently while using Ubuntu 7.04 in Gnome with the NVidia Restricted Driver enabled I get complete system lockups requiring a hard-reboot. When this happens the screen becomes mostly white with a random scrambled pattern of mostly-black lines. This happens even more frequently if Beryl or Compiz are enabled, but I have had it happen many times even when neither of these are running. There does not appear to be any specific action that is causing this behavior. It happened once while surfing in Firefox, once while setting up new accounts in gAIM, once while installing packages with Automatix, etc. I have yet to have this problem when I do not have the Nvidia restricted driver enabled, however I have not spent a lot of time in the system without this driver, as the usability of the system without graphic drivers is very limited in my opinion. This happens for me several times per week. The hardware seems pretty stable when running other Operating systems (my testing in other OSes with this equipment was pretty limited). The system is running very cool, so no signs of overheating. There was some mention in the forums of possible problems with Processor Stepping ("cool 'n' quiet mode"), I haven't made a lot of changes to BIOS settings yet, so I cant confirm/deny that this is related, but I have a suspicion that this is more related to how the Kernel is interacting with the video drivers. Hardware Profile: Biostar Geforce 6100-m9 Motherboard (On-board Geforce 6100 video) AMD Athlon 64 3400+ Venice 1GB PC3200 Memory (I have tried both the AMD64 and X86 versions of Ubuntu, and experience the same problem in both environments) Several complaints that seem to be related have been discussed in the forums here: http://ubuntuforums.org/showthread.php?t=405993 and http://ubuntuforums.org/showthread.php?t=402580 + + [Additional info] + bug 94739 reports similar info, particularly noticeable with Blender. Switching drivers and distro seemed to affect frequency but did not eliminate it. Disabling /etc/init.d/powernowd resolved the issue for the user.
