Subject: Re: I/O hangs after resuming from suspend-to-ram

Hello.

Addressing your questions below.

> Can't reproduce even with putting dmcypt on raid10 after applying my 
> patch.

Just a side note, that dm-crypt is not necessary here — I am able to 
trigger hang with RAID10 and LVM only.

> BTW, could you share us which blk-mq scheduler you are using on sata?

Okay, now it makes sense. Previously, without your patch I was able to 
reproduce the issue with "mq-deadline", "bfq" and "none". Now, I cannot 
trigger it with "none" set, but "mq-deadline" still hangs for me. Does 
this mean each scheduler should be modified separately?

> Could you apply the following debug patch and provide the dmesg log

Is it still relevant since I confirm issue to be fixed with "none"?

Thanks.
