lockups on Dell OptiPlex 780

Hello All,

Recently I moved back to a physical desktop at work, a Dell OptiPlex
780. Since installing 10.2-RELEASE, I've experienced some lockups, and
even since upgrading to newly released 10.3-RELEASE.

I was wondering if anyone has any ideas if this is good or bad. I
noticed this in the logs. During a lockup, I have yet to ssh into the
box physically, however I see if this can be done next time.

Here is a link to a run of dmidecode:
https://people.freebsd.org/~jgh/files/dmidecode_log.txt

My desktop didn't need to be rebooted until 1pm, but I am not sure if
the above errors are related or not.

If there is anything I can provide that may be more helpful, please let me know.

Thanks!
