Seems my system got another trap 12 error, and I managed to grab a dump
and run it through gdb. I don't know enough about the kernel internals to
make much sense of anything though. I would appreciate any suggestions.
If you need more info, please let me know. It appears to me that, for
some reason, there is a null pointer reference in if_de.c ?
I am using 4.2-STABLE from around 11pm Eastern on Dec 17th. These trap 12
errors were also occuring with 4.2-RELEASE. This hardware was running
correctly on 4.1.1 for about 4 months. Problems started about 4 days
after upgrading to 4.2-RELEASE. I've already added additional cooling to
the system, and reseated all the components.
dmesg, kernel trace and kernel config follow below.
Thanks,
- Richard
