Description Eric Anholt 2006-07-17 12:17:34 UTC 
When starting X on the EXA branch (commit
04d1584737fd0d14e99608a97281fd7b1549ae0e plus disabling the noisy debug printfs)
on my i915, the server exits partway through gnome startup with the hardware
hung.  If I set EXANoComposite (so the driver's composite handler never gets
called), it doesn't hang.  After using EXA without EXANoComposite and hanging
the chip, going to EXA with EXANoComposite also hangs.  Log to follow.

I should really fallback in 'repeat' for i915, which is not well support now.
I think that's why the engine hang, the second hang is caused by the corrupted
state, so reboot is needed. I'll commit patch to disable repeat for now.

Fixed this bug a week or so back.  Now it's just rendering all wrong (white
text), but not hanging.
