That means o2dlm is not the cause for the process hang.
Next, run ps:
$ ps -e -o pid,stat,comm,wchan=WIDE-WCHAN-COLUMN
Run it 6 times in 10 sec interval. This should tell us the processes
in D state and the location in kernel. Hopefully.
The next step is to to get the stack trace. alt-sysrq-t. That is more
invasive... so won't recommend it yet.
