At least from what I see in this transid error, unless you ruled out the
possibility of bad disk firmware and LVM/LUKS, it's hard to say it's
btrfs causing the problem.
In fact, we have a more experienced sysadmin, Zygo, sharing his
experience of bad *HARDWARE* causing various Flush/FUA problem, which is
not easy to hit in normal use case, but only after power loss.
So for your transid error, it's really hard to pin down the cause,
unless you have deployed hundreds btrfs...

As already said in that thread, full dmesg of that mount failure.
