Assigning to Mesa product.

>From this error dump, hung is happening in render ring batch with active head
at 0xfc71efe4, with 0x7b000005 (3DPRIMITIVE) as IPEHR.

Batch extract (around 0xfc71efe4):

0xfc71efd4:      0x78490001: 3D UNKNOWN: 3d_965 opcode = 0x7849
0xfc71efd8:      0x00000001: MI_NOOP
0xfc71efdc:      0x00000000: MI_NOOP
Bad length 7 in (null), expected 6-6
0xfc71efe0:      0x7b000005: 3DPRIMITIVE: fail sequential
0xfc71efe4:      0x00000104:    vertex count
0xfc71efe8:      0x00000006:    start vertex
0xfc71efec:      0x00000000:    instance count
0xfc71eff0:      0x00000001:    start instance
0xfc71eff4:      0x00000000:    index bias
0xfc71eff8:      0x00000000: MI_NOOP
