Sam, there were workaround for SKL and improvements pushed in kernel and Mesa that will benefit to your system, so please re-test with latest kernel & Mesa to see if this issue is still occurring. In the meantime, assigning to Mesa product. From this error dump, hung is happening in render ring batch with active head at 0x2b85163c, with 0x78150009 (3D UNKNOWN: 3d_965 opcode = 0x7815) as IPEHR.

We don't have enough information. - What kernel version are you using? (uname -a) - What Mesa version are you using? (glxinfo | grep Mesa) Please test a new version of Mesa (12 or 13) and mark as REOPENED if you can reproduce and RESOLVED/* if you cannot reproduce.
Dear Reporter, This Mesa bug has been in the "NEEDINFO" status for over 60 days. I am closing this bug based on lack of response but feel free to reopen if resolution is still needed. Please ensure you're supplying the correct information as requested. Thank you.
