With 2.6.33-rc1 I have random hangs. Even SysRq-Key works, only hard reset.
I've had it mostly within X, where I didn't get any messages but one time on
console with the following trace:

Since the system didn't respond anymore, I had captured this with camera and
copied by hand. I hope I haven't made any mistakes when copying. The picture
wasn't very good.

Wow, hard work. :)

I'll try it. The problem is, I haven't a workload, I can reproduce the hang
reliably. :(
