[Intel-gfx] [Regression 3.10.0+] i915 resume problem: pipe state doesn't match!

[Knut Petersen]

Hi everybody!

During resume from S3 there is a pipe state problem

Reproducibility: high (3 of 3 test resumes)

Hardware: Aopen i915GMm-hfs, Pentium-M, opensuse 12.3,
kernel 3.10.0+, git 496322bc91e35007ed754184dcd447a02b6dd685

Three slightly differing trace attached.

cu,
   Knut
