kgdb script

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

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

Then save the output here.  The kernel panicked because one of the cores failed
to respond to an interrupt, and it's not clear to me what that core was doing
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
