[PATCH 0/2] Support/debug for slow GuC loads

[John.C.Harrison@Intel.com]

From: John Harrison <John.C.Harrison@Intel.com>

Sometimes the GuC load is slower that it should be. For end users,
that usually means some kind of thermal throttling issue. Internally,
there can be any number of bugs that cause it. So don't completely
fail to load, just cope with it and report the problem.
