For now I've turned off journaling (soft updates seem fine) and that

Let me know if I can provide more details etc!
I'm not sure, but this may be an after-effect of known problems right
now with SU+J on 9.0. It would help if you could state if you're using
"dump -L" or not.
I've seen the "deadlock" behaviour you describe on older FreeBSD
versions (dating back to at least 7.x) when using "dump -L", which
generates a fs snapshot. Obviously 7.x does not have SU+J, so I'm a
little surprised disabling journalling fixes the problem for you.
It's a known bug: SU+J currently deadlocks when used with UFS snapshots.
