There is a recent ML report that mounting a large fs backed by hardware RAID56 controller (with one device missing) took too much time, and systemd seems to kill the mount attempt.
In that case, the only error message is:
BTRFS error (device sdj): open_ctree failed
There is no reason on why the failure happened, making it very hard to understand the reason.
At least output the error number (in the particular case it should be -EINTR) to provide some clue.
