--- Comment #10 from Francisco Jerez <currojerez at riseup.net> ---
Changing product category of the bug to Beignet.  Beignet shouldn't assume that
the MOCS tables are set to the hardware defaults, but instead use the MOCS
values exposed by the kernel.  The kernel-defined MOCS entry 2 is roughly
equivalent to the hardware-default entry you seemed to be using previously, the
(completely untested) attached patch should fix the issue.
