Hello,

I'm running wow in wine on 64 bit fedora rawhide on a dell vostro 3550
(i5 with integrated GPU).

I'm reliably able to produce 2 types of crashes:
- wow freezes, but I can get to text console, in this case I'm able to
  grab a kernel stack trace  (below) prior to seeing the normal
  [drm:i915_wait_request] *ERROR* i915_wait_request returns -11 (awaiting 452684 at 452608, next 452686)
- the other is a complete freeze of the system, hard reset required, nothing logged to /var/log/messages

Is there any value in me creating a bug report for this, it seems to be a pretty common issue.
Is there any use in my trying different kernel command line optios for the i915 driver
or config options to the xorg intel driver?

I have the various git trees pulled out (I was looking for recent changes that might be related
to this issue).  I'm capable of building and installing from these git trees if there are specific
bits that I should test.
