I had a kernel panic this morning on a production machine, also running
3.10.9. I only got a small part of the end of the trace, but it matches:

Kernel panic - not syncing: Fatal exception in interrupt
Machine was running for a few days before panic'ing. I don't see anything
in 3.10.10 that would've affected this.
Thanks!
