<pre>From your latest error dump:
render command stream:
HEAD: 0x00e1bbe0
head = 0x0001bbe0, wraps = 7
TAIL: 0x0001c780

Even on Mesa master-9036887, the hang is still HiZ's fault :(
Hangs are always difficult to diagnose, so I apologize beforehand for how much
turnaround it may take to solve this.
I have some actions and questions for you:
- Is your Mesa build unpatched? Or does it include patches from the RPM? This
is critical, because some Fedora Mesa SRPMS contain already contain a HiZ
workaround patch that may intefere with upstream. If your RPM contains patches,
please provide the full SRPM. (I can pull from
git://pkgs.fedoraproject.org/mesa if that makes it easier).
- Which version of xf86-video-intel? Can you point to a SRPM?
- Please try to reproduce with Mesa master-6a5c86f. The commit immediately
after that removes a "redundant" HiZ workaround. Maybe it wasn't redundant
after all.
- If you can still reproduce with Mesa master-6a5c86f, then please also try
with tag mesa-10.0.2.
- What is the mean time to failure after a reboot?
- How exactly are you reproducing the hang? By zooming and out on New York
City for 4 hours? By rotating the earth left continuously for 30 minutes near
the equator?</pre>
