I dare say the third party (*cough* BIOS *cough*) that re-enabled VGA behind our back also did so without device ownership leaving a MMIO_DEBUG fail behind. Note that we never truly takeover from the BIOS here as i915.disable_displays=1 doesn't do what it says on the tin.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> <li>You are on the CC list for the bug.</li> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
