I finally got a full stack trace via sysrq. A lot of stacks seem to
end in page fault -- I wonder if its because my page file is a
loopback on btrfs.

I switched to the LT kernel because of this issue. I was running
mainline and thought that LT would get me stability. I can switch
back to LT while we RCA.
At the risk of changing two things, I could add that
(scsi_mod.use_blk_mq=n) to my boot and also switch back to ML. I do
notice that disk

I don't know if it's the sending MUA or the list server, but the line
wrapping makes this much harder to follow. I suggest putting it in a
text file and attaching the text file. It's definitely not on the
receiving side, I see it here also:

Ok, caught the hung tasks last night. I don't *think* this is
related, because I pretty sure this isn't happening on the same
filesystem, but I do have a loopback swap on one btrfs drive.
The hang might have occurred after the btrfs balance was finished
which is confusing. I'm adding

Just wild first guess... are you also
What's also confusing is I just ran a manual balance on the fs using
defaults (which are aggressive) and it completed with no problems.
It smells more like a race condition than a particular corruption.

I'm running 4.4.106-1.el7.elrepo.x86_64 and I do a btrfs balance everynight.
Every night I'm getting a kernel hang, sometimes caught by my
watchdog, sometimes not. Last night's hang was on the balance of DATA
on / at 70.
I'm not sure how to further trace this down to help you -- the console
