system randomly freezes, must hard reboot

[hypermegachi]

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.

i've just tried running with regular Xorg with vesa, and my computer hung again. this time the mouse pointer froze completely.

i'm thinking it might have to do with my ndiswrapper being unstable, because it crashed when i started up gaim.

anyways, i recompiled ndiswrapper from source, let's see if it fixes the problem.

compiling ndiswrapper didn't fix it.
the logs don't say anything weird or unusual (at least i don't think they do)

they weird part about this is that my music is still playing. i have mpd running in the background, and the entire song plays from beginning to end. i didn't wait to see if the song goes on to the next track, but it was a good 2 minutes. the keyboard didn't respond and i couldn't ctrl+alt+f1 to another console.

Sounds like the kernel isn't completely dead. Without having a login this could be hard to track down unless removing something makes the problem go away. The problem could well be ndiswrapper though...

This bug also happens to me, i am pretty sure it is because of ndiswrapper, since it only happens when i am using my wireless card, and there is some traffic on it. If i am on a wired connection this problem doesn't show up.

confirming as more than one person stated they had the same issue. affects ndiswrapper, unless someone can prove otherwise

Could you try this using gutsy and/or latest ndiswrapper?

Also provide more info if your problem isn't fixed in gutsy or latest ndiswrapper.
uname -a
ndiswrapper -v
dmesg > dmesg.log
