tested -next 07-31, where this one doesn't occur, but v4.2-rc6 is still affected
Can you test http://lists.freedesktop.org/archives/intel-gfx/2015-August/073406.html and http://lists.freedesktop.org/archives/intel-gfx/2015-August/073405.html ?
I tried test these on 4.2rc5. The "cleaner" patch gives a similar backtrace to before. The other one doesn't apply cleanly to 4.2rc5 or 4.2rc6. The chunk at 13267 in intel_display.c changes a line that doesn't exist. Is there another patch needed before this?
sorry, I get it, you wanted both patches at once... With both patches applied it does seem to solve the issue. Thanks!
The patches have been applied, closing. Thanks for the report.
