Can someone decode this Code: line into something useful please?
(maybe we should put in an instruction decoder as well as kallsyms
into the kernel? 8))

You can just feed that single line into ksymooops. As long
as you have an x86 machine ;)
mnm:/home/akpm> echo "Code: f6 80 1c 01 00 00 02 75 2d 8b 4d 08 51 e8 10 6e 00 00 85 c0" | ksymoops

Is there a bingrep, so that you can grep for that binary string in
vmlinux (or whatever it's named)?
If not and you haven't already written one, you can use my
binoffset program for that. It might help your search time.
It's at
