Hi dspence
I'm afraid I don't have any good answers for you, but maybe
a few ideas to try to make some progress on this.
Maybe the contents of dmesg can provide some insight by
saving a copy when the coredump occurs.
Maybe use inotifywait to monitor /data/coredumps for a
file to be created, and then trigger:
dmesg > dmesg$(date +%F-%T).txtThat should create dmesgYYYYMMDD-HH:MM:SS.txt every
time a coredump occurs.
If you need help with that, I can provide a sample of how I
used inotifywait to trigger a command when a file gets created.
I also found this about using gdb to generate a coredump file:
