decoding kernel oops

Hi,

I was going through this post
http://kerneltrap.org/mailarchive/linux-kernel/2008/1/8/546623 and
couldn't understand the steps around the below paragraph.

"
and run it under gdb, and then when it gets the SIGSEGV (due to the
obvious NULL pointer dereference), I can just ask gdb to disassemble
around the array that contains the code[] stuff. Try a few offsets, to see
when the disassembly makes sense (and gives the reported EIP as the
beginning of one of the disassembled instructions).
"
Has anyone tried this ?? I don't see any useful disas instructions
when I do so ... Need help in interpreting the procedures of the above
post.
