Ok one thing I did notice: [ 0.000000] efi: No EFI runtime due to 32/64-bit mismatch with kernel You're using a 32-bits kernel with 64-bits efi runtime. Not harmful in itself probably. Could check if it goes away with noefi though.. Taking a closer looks at the reverts: There appears to be a bug in the plane disable code where the call intel_disable_primary_hw_plane does nothing. This isn't noticed because the primary plane gets disabled through intel_disable_sprite_planes. I'm guessing the attached patch might solve the issue too. Can you check?</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> </ul> </body> </html>
