--- Comment #6 from yann <yann.argotti at intel.com> ---
Terence, please use latest drm-tip ()

it looks like we have a loop of MI_SEMAPHORE_MBOX command (wait upon the
semaphore value remained ?) with blitter ring (any relationship with bug
54226?)

You may also try to add drm.debug=0xe in your boot command line to collect more
data.
