dmesg output with kernel stack trace
Also, when I turn the monitor off and then back on I get the following in dmesg.
Please try Ville's FIFO underrun elimination series [1] on top of drm-intel-nightly, also available at [2], and report back. [1] http://mid.gmane.org/1446146763-31821-1-git-send-email-ville.syrjala@linux.intel.com [2] git://github.com/vsyrjala/linux.git pch_fifo_underrun_fix_4 Please re-open the bug if the issue still exists on the latest drm-intel-nightly. I am closing this as there has been no response for some time now. |
