I didn't see this in the previous messages, but have you tried temporarily
remounting the filesystems read-only if you can't unmount them?

Also, earlier you mentioned looking at /var/log/dmesg for write errors.  On
my systems, that only contains a snapshot at boot. I have to run dmesg to
see the latest updates. It seems suspicious to have nothing in the dmesg
during 61 days past 10 seconds after system boot ...
