--- Comment #4 from cprigent <christophe.prigent at intel.com> ---
>From error dump, hung is happening in render ring batch with active head at
0xff2057e4, with 0x7b000005 (3DPRIMITIVE) as IPEHR.

Batch extract (around 0xff2057e4):

0xff2057c0:      0x780c0000: 3D UNKNOWN: 3d_965 opcode = 0x780c
0xff2057c4:      0x00000000: MI_NOOP
Bad length 7 in (null), expected 6-6
0xff2053c8:      0x7b000005: 3DPRIMITIVE: fail sequential
0xff2053cc:      0x0000000f:    vertex count
0xff2053d0:      0x00000003:    start vertex
0xff2053d4:      0x00000000:    instance count
0xff2053d8:      0x00000001:    start instance
0xff2053dc:      0x00000000:    index bias
0xff2053e0:      0x00000000: MI_NOOP
0xff2057e4:      0x05000000: MI_BATCH_BUFFER_END
0xff2057e8:      0x00000000:    
0xff2057ec:      0x00000000:    
0xff2057f0:      0x00000000:    

Should we assign to Mesa team? Or does it need investigation from GuC side?
