** 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:

+ [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.
