Questions regarding use of 'gdb -k'

[Kent Kuriyama]

I am having difficulty in using 'gdb -k' to track down a kernel panic.  I 
have built a version of the kernel with the debugging symbols.  After 
the crash I use the 'gdb -k' command but get the following output:

Can you tell me what I am doing wrong?  Thanks.
