The configuration register was changed since last restart ??

It's not showing nothing, but we never know.. :)

With that symptom was excepting to see :

Configuration register is 0xyyyy (will be 0x2102 on next reload)

There are a lot of reasons that the switch may have been restarted and not all of them are switch issues. I'd hate to rehash old questions but these are the basics that might need to be run through first:

1. Is the switch on an UPS?

2. Are both power supplies on the same circuit?

3. Is the switch in a secure room?

4. Who else has access to the switch?

Often I find that my issues are the result of either overtaxed circuits or someone kicking a power cord.

Do you have any type of system logging? The event was over 2 weeks ago so show log will most likely not show any events that happened before the restart but it might be worth a look. You also may want to see a 'show power' and make sure you aren't overtaxing the power supplies.
