Comment 11 for bug 492392

I've also had this problem for some time on 2.6.32 since the early RC's, this commit completely fixes the problem here but does not apply to 2.6.32.y and a fixed up one has not been submitted to stable yet.

http://git.kernel.org/?p=linux/kernel/git/anholt/drm-intel.git;a=commit;h=cf74ecbbff3e3b45bae61d28d2220f74d853e2f0

Late in the 2.6.32 development time drm-intel-next did fix the random flickering after resume for me, but the hanging on a solid color still happened eventually until the above commit.

Here is a bug on the kernel bugzilla regarding it:

This problem also affects some people on other distros as soon as X starts, but for me it is only triggered after a resume.
