Once the task is dispatched to HW at ****, it is completed async, i.e.
it may be completed and freed at any point, even before the dispatch

you will prob see it yell like I saw.
I too have similar thought here. After dispatch to HW, no point to touch the
task state. But since the code is in IO path, may need further testing.
Hi,
Have you made any progress on the hang which I see on my arm64 system?
I think that you said that you can also see it on an arm64 system -
would that be with a similar card to mine? I think mine is 8008/9
I have tested some older kernels and v4.11 seems much better.
Thanks,
John
