I'm assuming from the lists you've posted to that this is under KVM? What disk drivers are you using (virtio or emulated)? Can you get a full stack backtrace of kjournald? Kevin Bowling submitted a RH bug against Xen with apparently the same symptoms (https://bugzilla.redhat.com/show_bug.cgi?id=526627). I'm wondering if there's a core kernel bug here, which is perhaps more easily triggered by the changed timing in a virtual machine.
