[68.196054] BUG: sleeping function called from invalid context at kernel/sched/completion.c:99

is a secondary error. These appears to be quite different bugs, a mixture of unrelated use-after-free.

Ok, thanks for your quick comments. Separate bug (Bug 109555 and Bug 109469) are created for the above failures. This bug is for 'incomplete' failure on ICL platform.
Comment 5 Martin Peres 2019-04-23 11:54:38 UTC 
Raising to highest, since it looks like a use-after-free.
Comment 6 James Ausmus 2019-04-24 22:45:13 UTC 
This is the exact same backtrace as 109084, only difference is 2x-flip-vs-legacy vs 2x-long-flip-vs-legacy. Marking duplicate of 109084
