Bug Description
Screen freezes black and locks up randomly. Only a hard reboot will bring it back.
Several others on Ubuntu Forums have reported similar problems.
Usually I have a fair amount of programs running when it happens. Memory issue? (I have 500 MB and don't run games or other memory hogs.)
Computer is a Dell Notebook 640C.

Similar problem. 'm not using any restricted driver and I have a fresh installation of the final feisty release! I'm on ati and I have 'desktop effects' enabled.
Here what happen: for no apparent reason (although it is somehow correlated with firefox) the CPU usage goes to 90% for about 20 sec. If during this period I open menus if I do something in a fast sequence the computer freezes: I can move the mouse but nothing responds, no <ctrl><
I also notice one thing. When the CPU usage peaks (90% or so), if I open the system monitor there are just 4-5 active processes using around 5% each. Weird!
Here are my specs: Dell inspiron 6000, intel pentium M (no dual core!), ATI Mobility Radeon X300
