Yes, I have narrowed it down. I did not run bisect, as it takes me 4hrs for kernel build on Eeepc...
The problem has appeared in 3.1-rc3, it is a regression. I have tested -rc1 and -rc2, they are OK ( not that there was much activity regarding i915 in -rc2). The problem is still present in -rc7.
I see these entries in the changelog, these are Keith's additions to -rc3 which maight impact the blanker:
Keith Packard (6): drm/i915: Wait for LVDS panel power sequence drm/i915: Leave LVDS registers unlocked drm/i915: Fix PCH port pipe select in CPT disable paths drm/i915: Remove unused 'reg' argument to dp_pipe_enabled drm/i915: Can't do accurate vblank timestamps with UMS drm/i915: Cannot set clock gating under UMS
I can do a fast incremental rebuild of my current -rc3 tree, if Keith could send me some patches...
Thanks, Woody
