another crash

[Brett Lymn <blymn%internode.on.net@localhost>]

I updated my -current amd64 machine last Friday (17/6) and in addition
to the coda crash I am seeing a kernel panic in what appears to be
kevent:

I don't know if it is related but the crash seems to happen when I am
running firefox.  I have yet to rebuild my packages so firefox is pre
the changes for address randomisation but that shouldn't matter I think.

I have a kernel core if more information is needed.
