--- Comment #1 from yann <yann.argotti at intel.com> ---
We seem to have neglected the bug a bit, apologies.

from gpu crash dump we can notice that there is a failure with Protected
Audio/Video Path :
ERROR: 0x00000028
    Invalid physical address in ROSTRM interface (PAVP)
    Invalid physical address in WRITE interface (PAVP)

There were 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.
