The kernel OOPS is just a result of previous GFX ring test failure. Attached
log from UMR shows gfx ring is hang around (or right after) first
PKT3_SET_CONTEXT_REG because latest PFP_HEADER_DUMP shows 0xc0d46900, this
points to possibly that some of the payload within SET_CONTEXT_REG (in
gfx_v8_0_get_csb_buffer) causes hang and later this results in ring test

Alex Deucher - Any idea how to confirm this ?
