tested "hammering" the ufs -

Excellent, that backtrace was very useful.
Here is an untested kernel source patch for you to try. You do need
to compile up a kernel to test this. A spinlock was being held
through a softupdates callback. The problem only occurs when running
on UFS (and since most of us run on HAMMER we didn't notice).
