Hi!
Suddenly /bin/sh started to crash all the time with core dumps. I'm
running FreeBSD 7.2-RELEASE-p4 (i386) and I have not updated anything
lately. The /bin/sh binary seems to be untouched. It might be some
hardware trouble, but the machine seems to run OK now. (I had to
replace /bin/sh with a symlink to /rescue/sh.)
I would like to track down the problem, but running sh I only get
"Segmentation fault: 11 (core dumped)". I would be happy to run
gdb and give you a backtrace. Any clues?

PS! I tried to run "freebsd-update IDS" to see if any files are
broken, but it stops at
Inspecting system... sha256: ///boot/kernel/utopia.ko.symbols: Input/output
error
All of this points to a hardware problem.
I think the best thing you can try is to manually get a hash fingerprint
of your sh and compare it with another, known good copy.
