Subject: Re: misc/183042: Machine kernel panic'ed, now fsck is
segfaulting

I was able to grab the fsck_ufs binary from a 9.0-RELEASE box and run it,
which worked. I was able to clean the filesystem and re-mount it.
Even _AFTER_ the filesystem was clean, the 9.2-RELEASE binary will
segfault.
Here is the truss output from running the 9.2-RELEASE binary on the clean
(unmounted) filesystem.
