This change was made by a bot.

[Joseph Salisbury (jsalisbury)]

Does this issue go away if you boot back into the previous kernel?

[Ralf Hildebrandt (ralf-hildebrandt)]

Which previous kernel do you have in mind?
Something from raring?

[Ralf Hildebrandt (ralf-hildebrandt)]

I'll boot into 3.8.x from raring and see what's going on there

[Joseph Salisbury (jsalisbury)]

You mentioned this started happening in a recent kernel. Did this happen in earlier Saucy kernels? Basically we would like to know what was the last good version and first bad version, then we can perform a kernel bisect.

[ 5.127462] [drm:intel_pipe_config_compare] *ERROR* mismatch in adjusted_mode.flags (expected 2, found 0)

looks like a duplicate of bug 1211976 and should be fixed by [0] when 3.11.4 lands in Saucy (bug 1237530).
