Re: [Xen-devel] double fault ...

You compile with crash_debug=y?

Yes.  Mostly to get a xen binary without optimization and with full
debug info, so I can easily lookup stuff using
        "objdump -dS xen-syms | less +/<addr>".

Probably 'debug=y' should also cause -g compilation. I'll add that in.

I presume you do 'optimize=n' to turn off things like -O3?

The intention is that do_int3() will execute DEBUGGER_trap_fatal()
before panic(), so you should enter the gdb stub rather than
infinitely loop. How is that not occurring?

I don't actually have a debugger attached, so DEBUGGER_trap_fatal
aka __trap_to_cdb() instantly returns.

I see. I'll check in a fix.
