find stuck in state "clock"

[Matthew Dillon]

:I couldn't find a commit that I can relate to a fix for that problem, 
:neither in -release nor in -devel.
:
:Ok, I tried to play a bit Sherlock Holmes (on the live system).
:
:I found:
:
:find blocks in cache_lock() on "/dev/ttyp5"
:
:This entry is locked by sshd in state vnode, waiting for an exclusive 
:lock on a vnode which is being locked by tcsh, which is in state ttywai. 
:  Guess on which tty: ttyp5.  Seems like a deadlock situation.
:
:Is there something I can look at?  I could try to get a dump tomorrow, 
:but I'd rather not, I should be busy at the moment.

    Well, there was a deadlock we fixed in spec_vnops.c/1.21, but that
    was from before the release. 

    The best thing to do is to get a kernel core and upload it to leaf.
