--- Comment #53 from David Kowis <dkowis+kbt@shlrm.org> ---
I'm uncertain if the problem I'm encountering is the same problem or not, but
it appears extremely similar. Forgive me if I'm not contributing properly.
I've got a Xen VM that is exhibiting the locking symptoms, but not the
corruption symptoms. A reiserfsck only replays journal entries and does not
find any corruptions. This is the only VM that does this out of about 14 VMs. I
see no error messages in the dom0 dmesg.
This is an ArchLinux distro Kernel 3.12.5-1-ARCH. it'll block anything that
wants to do IO, the kworker here, and dropbox as well. Eventually it gets to
the point that the system wedges and dies. I can Emergency Sync it via xl
sysrq, but it won't shut down cleanly. I have to xl destroy it. My other VMs,
some with higher IO loads are on 3.11.6-1-ARCH and have no problems.
