[Intel-gfx] Fedora Core 12 x86_64 lockup/crash

[Avedissian, Vahe Y (AS)]

Hi Clemens,

You were right. The kernel was not crashed and I was able to ssh to the machine. I have attached the dmesg output.
There is an error about dereferencing a NULL pointer...

I tried invoking pstack with the X pid and it just hangs...

Is there anything else I can try?


Thanks,

Vahe
