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.
