So I originally thought this one was shutdown related (there still may
be a shutdown hang, I was quickly working around other issues to give
priority to the corruption issue), but what I'm seeing actually looks
like a log reservation deadlock. More specifically, it looks like a
stuck CIL push and everything else backed up behind it.

I suspect this is related to the same patch (it does show 4 concurrent
CIL push tasks, fwiw), but I'm not 100% certain atm. I'll repeat some
tests on the prior commit to try and confirm or rule that out. In the
meantime, dmesg with blocked task output is attached.
