--- Comment #9 from Eero Tamminen <eero.t.tamminen at intel.com> ---
This time SKL GT4e did have recoverable GPU hang in SynMark (CPU<->GPU sync)
Terrain tests, instead of in HdrBloom like SKL GT2 & KBL GT3e had.

KBL GT3e recoverable GPU hang dmesg shows some additional issue:

[ 1822.876414] GPU hangs can indicate a bug anywhere in the entire gfx stack,
including userspace.
[ 1822.876415] Please file a _new_ bug report on bugs.freedesktop.org against
