可以的. gdbstub
gdbstub introduce in the khg in first page the 15 item ,khg is a very
famous site,kernel hacker beginner 's page :
http://www.redhat.com:8080/HyperNews/get/khg.html
the gdbstub is available at the site:
ftp://ftp.gcom.com/pub/linux/src/gdbstub/gdbstub-2.0.36.tar.gz.

I think you may be can use another kernel debugger if you had only one
machine.

ftp://hyper.stanford.edu/pub/pcmcia/extras/kdebug-1.6.tar.gz
ftp://ftp.ocs.com.au/pub/xkdebug-2.1.55.tgz (x version)

I use gdbstub once ,but I don't know how to set breakpoint
in the kernel source,and I can't see the kernel source too.
I don't know why,maybe you can get it.
