GPU hanging(?) with latest mesa packages

[Ian Pilcher]

I just tried the new mesa* packages in Fedora 15 updates-testing on my
Sandy Bridge (Core i7 2600) system, and the results were not pretty.
X was completely unusable, with both of my screens "flashing" solid
black every few seconds.

These messages appeared in the syslog:
