Just about anything is possible. All we seem to know at this point is that
it is some change that went in between 7.1->7.3. It also doesn't appear to
be the only change that was done to the nfs server during this period.

Any change applied to the aac driver might be a factor, but??

Is anyone else seeing this problem (nfsd threads stuck in wchan "ufs")
on FreeBSD7.3?
