[Bug 39832] system randomly freezes, must hard reboot

[hypermegachi]

Public bug reported:

I started noticing this problem when I installed XGL.  Basically, my
system would freeze up, under heavy or no load, at random intervals.
The only way to get control back is to hard reboot the system.  Oddly
enough, I can still move the mouse and the cursor moves around the
screen, but I can't click on anything and the keyboard doesn't respond
either (numlock doesn't flash the light).

I figured that maybe it was XGL, so I pointed the symlink back the Xorg,
but the problem remained.  I've tried using radeon drivers, fglrx
drivers, and both do the same thing.  I also tried using an older 386
kernel, but it froze again.  So, I'm not even sure if XGL is the
problem.

Here's some hardware details:
P4 running at 2.1GHz
Radeon 8500LE
512 ram
zd1201 wireless usb stick (using ndiswrapper)

Let me know if you need more details and/or logs.  Thanks.
