[Bug 97020] [hsw] GPU hang on first context use (after long uptime)

--- Comment #5 from Chris Wilson <chris at chris-wilson.co.uk> ---
The "bogus alignment" errors are themselves bogus (self-inflicted by the kernel
and don't affect anything). The hang is on processing the MI_SET_CONTEXT. This
kernel has the workaround for the PSMI issue, so hopefully it is not a repeat
of the last known context hangs, but I did find that this was a fresh context
of interest. Could be some state that hasn't been cleared etc.
