[Xen-devel] Re: about kdb for Xen

[Mukesh Rathor <mukesh.rathor@xxxxxxxxxx>]

You cannot continue execution when system crashed. The only thing to do is 
reboot. So go is disabled, as sometimes accidentally one might type that while 
debugging.
There is some work to get gdb to debug xen, but I'm not sure what state it's in.

To assist in debugging via kdb, use gdb on xen-syms file. Then use gdb to find 
 matching line numbers in C file. Look at gdb manual how to do that.
Thanks,
Mukesh
