Hi Artturi,

I applied your diff:

KASSERTMSG(xfer->nframes == 0 || xfertype == UE_ISOCHRONOUS,
"nframes %d xfertype %d\n", xfer->nframes, xfertype);

Now system freezes without crash :-(

Also, after that many crashes, the filesystem has become quite corrupted.
I am currently using one big fs mounted on “/“ with option softdep.

# mount
/dev/sd0a on / type ffs (local, wxallowed, softdep)

Is use of softdep still recommended?
