Xorg log (shows some errors and warnings)

Description of problem:
I installed and updated F10 Alpha last night and the intel driver is slow, switching windows can take a while to redraw etc.  It looks like it has to do with GEM according dmesg and Xorg.0.log, I will attach those log messages.  This is occuring on a Thinkpad T61 with a GM965 graphics chip.

Version-Release number of selected component (if applicable):
xorg-x11-drv-i810-2.4.2-8.fc10.x86_64
xorg-x11-drv-i810-2.4.2-7.fc10.x86_64


How reproducible:
Seems performance may be degrading over time.

Steps to Reproduce:
1. Run xorg
  
Actual results:
Slow window redraws

Expected results:
More responsive UI

Looks similar 460776, but probably not a duplicate (that bug has some kernel errors reported as well).
Comment 3 Bastien Nocera 2008-11-25 13:06:38 UTC 
Might be an MTRR problem like bug 444328
Comment 4 Bug Zapper 2008-11-26 03:03:47 UTC 
This bug appears to have been reported against 'rawhide' during the Fedora 10 development cycle.
Changing version to '10'.
