I purged the oibaf ppa, revert to mesa 10.1 stable with no luck, just to check that the problem is not in mesa. But reverting drm/i915: Wa32bitGeneralStateOffset & Wa32bitInstructionBaseOffset still fix the hang. Once i noticed after gpu hang in dmesg (i don't know if it is important): [drm:intel_set_cpu_fifo_underrun_reporting [i915]] *ERROR* uncleared fifo underrun on pipe C I also find that switching VT with CTRL ALT F1 is not working since 4.4-rc1, i just have a black screen with nothing displayed on it, but typing something (in the dark sudo reboot) is working. But i suppose that this is a separate issue.</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>
