Having just remembered that the install kernel has ddb built in we had a
little poke. trace gives the (not very informative) output
(null)(c082bd60,cb002eb8,c02b127e,1,cb002ec8) at 0xc024cce0
(null)(1) at 0xc02b12c7
Bad frame pointer: 0xc0839780
and ps shows pax is waiting on "uvn_fp2" and as you would expect there are few
other processes running (sysinst and some kernel processes)
We have a machine in this state at the moment if there is something we can
usefully do with it to help track this down.
