kgdb script

Thanks.  Now, please try downloading the attached file, and run:

# printf "source /path/to/acttace.py\nacttrace\n" | kgdb83 /boot/kernel/ker=
nel
/var/crash/vmcore.2

Then save the output here.  The kernel panicked because one of the cores fa=
iled
to respond to an interrupt, and it's not clear to me what that core was doi=
ng
at the time.

It would also be helpful to see output from:

# kgdb /boot/kernel/kernel /var/crash/vmcore.2
(kgdb) tid 100168
(kgdb) frame 4
(kgdb) p other_cpus
