Hello Hong Liu,
Could you have a look at
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=465921 ?
Sylvain Ferriol reports a regression in 2.2.0.90. He found out that the
breakage occured in one of your commit (see below).
Sylvain, could you tell us what was the last commit on top of the
xf86-video-intel-2.2-branch that you tried before git-bisecting ?
Thanks,
Brice

hello
after upgrading to 2.2.0.90-2, my X server is unusable. lots of pixels blink
and the text is unreadable
Which driver did you have before ? 2.2.0 ? Can you try to git-bisect the
upstream git repository (on the xf86-video-intel-2.2-branch) to locate
the bad commit causing this? Let me know if you need help.
ok the bug is in the 4e5c7... of 2.2-branch:
Bug 10773: fix i8xx pll p2 value in i830_crtc_clock_get()
Also fix debug dump, slightly modified to use macro instead.
and in the code:

Also, note that your dual-head config in xorg.conf is obsolete (multiple
Device and Screen sections, for instance). You should read
http://wiki.debian.org/XStrikeForce/HowToRandR12 to cleanup all this (or
just remove your xorg.conf entirely). Let me know if you need help, again.
