deadlock detected in -current (new).. NFS? Anyone with 'amd' knowledge?

Anyone seen these recently?



I just got the following:

panic: deadlkres: possible deadlock detected for (address)  blocked 
for (big number) ticks

anyone seen similar on very new (yesterday) -current GENERIC. ?
there was a prior message that may or may not be related:

newnfs: server pid741_at_gamma  error: fileid changed. fsid 0:0: expected 
fileid 0x1, got 0x2
(BROKEN NFS SERVER OR MIDDLEWARE)

(amd screwed up).

I suspect that amd is broken on -current
using known good config files results in a hung nfs mount
and even after killing amd, any attempt to touch the mountpoint 
results in a hung (but interruptable) proccess.
For example as /net  was an amd mountpoint,   ls -l /    results in a 
hung copy of ls.
(but you can get it back with ^C)

I suspect the two are related.
