Hi Dave,
One thing re: x86_64 -- unlike x86, please create your own
xen-specific
backtrace function to plug into the machdep->back_trace function pointer.
I'm pretty sure you won't be able to make the current version work
for xen!
Yes, I'm investigating now. "bt" is more difficult than other command.
Thanks.
