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><alt><Bckspace> or <ctr><alt><del>. The only thing I can do is
<alt><prnt scrn><b>.
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
