Just to knock out a couple things...

looks like the forced shutdown path leaks some zone allocations; hard to know
for sure which zones from this info.  If it happens again, check /proc/slabinfo
to see which xfs zones are still there.

After that,

this is expected, since the zones did not get cleaned up before.  A reboot
will take care of that problem.

The original traces - were those oopses?  Looks like you edited them a bit
too much.

Thanks for trying to save out the first part of the device; we'll need to look
and see if by chance that'll be useful.

in-memory corruption does not necessarily mean bad memory; it just means that
some in-memory variable was not as expected.  This could be due to any number
of reasons.
