I was shutting down my amd64 system with reiser4-for-2.6.14-1.patch.gz
on 2.6.14.2 when I got the output below. I haven't had the problem
before and probably couldn't reproduce it easily. I can provide more
details if requested, but I left out the contents of all the registers
because I was transcribing from digital photos.
