I'm seeing a lot of messages like this:

          vnode sez 0xffffffff80b76b90, listhd 0xffffffff80b76b80

  on my machine.  It's a T61/amd64 running -current from yesterday.

Me too, on

  Thinkpad 600E (i386)
  current from end of last week
  1 processor
  ffs
  coda, but coda usage doesn't seem correlated

after a long time the machine crashed with locking against myself.

I'll be updating/retrying anyway to get the softdep panic fix.
