I am typing this after a clean reboot and already got the GPU hang again. It happens about every few minutes. Are you really sure this is the same GPU hang as in <a class="bz_bug_link bz_status_ASSIGNED " title="ASSIGNED - [snb 3.5] stale semaphore sync seqno (typically as seen on bcs->rcs)" href="show_bug.cgi?id=54226">bug 54226</a>? I didn´t have this before 4.1 kernel? Also I note that I still use Option "AccelMethod" "uxa" and I have martin@merkaba:~> cat /etc/modprobe.d/i915-kms.conf options i915 modeset=1 i915_enable_rc6=7 thus maximum energy saving. But according to powertop it never enters the highed sleep state anyway. I will remove the AccelMethod setting now and see whether it helps. If not, I downgrade to 4.1-rc4 for now, as issues have been at least much less frequent with it.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
