Hello,
I'm sorry to bother you, but you may not be aware of this thread and
this problem. We are several people experiencing deadlocks, kernel
panics and other problems when creating sanpshots on file systems
with SU+J. It would be nice to get some feedback, e.g. how can we
help debugging and / or

Hi,
I've seen this too (and other problems with SU+J and snapshots) and was
able to reproduce it fairly easy. I wrote a PR:
http://www.freebsd.org/cgi/query-pr.cgi?pr=163310
Never received any feedback until now...

I have a RELENG_9 machine that hangs when a snapshot is created on the
root fs (UFS, with SU+J). More accurately, all the processes show a
state of "suspfs" (with ^T) and no fs activity is completed from then
on. A hard reboot (power cycle) was the only way to proceed.
