Hi All,

I've been hunting around for information on how to help debug the issue
I'm having - Hopefully someone here can help

My setup is:
 - ASRock Z68 Pro3 Gen3 motherboard
 - i5 2500K CPU
 - Fedora 16
 - Vanilla 3.2.0+ kernel (commt ccb19d263fd1c9e34948e2158c53eacbff369344)

I'm experiencing frequence total system freezes (not even reset button
works). I originally thought it was a power management problem because the
freezes only seemed to occur after leaving the system idle for a while,
but recently the freezing seems to be happening even when the machine is
in full use.

I have not seen many other reports involving the Z68/HD3000 combination

I have submitted a bug report on the kernel bugzilla tracker:


This has /var/messages and Xorg logs, but neither show anything
particularly interesting (no oops for example)

I've tried netconsole, but no additional messages are appearing there

I've also tried i915.semaphores=1 to no avail

So I'm open to all and sundry suggestions. I'm willing to build and run
developmental / experimental code, apply patches etc to help identify the
problem / test potential solutions.
