[c-nsp] 6500 - stateful failover, reason?

Drew,

You should have a crashinfo file on the used-to-be-primary SUP
bootflash.
The right thing would be to open a TAC case, and give the engineer the
crashinfo file and the show tech for the device.

Is there any way to get more information about what caused a fail-over
between two supervisors in a 6500?

All I can appear to get is "Active crashed." from show redundancy
switchover and my syslog doesn't have any information either.

Also, is it normal that during switchover you will lose protocols (OSPF)
and that you will see messages like these in the log?

Sep 22 08:41:17.651 EDT: %C6KPWR-SP-4-PSOK: power supply 1 turned on.
Sep 22 08:41:17.699 EDT: %C6KPWR-SP-4-PSOK: power supply 2 turned on.

The log messages sort of confuse me because show version indicates:

uptime is 10 weeks, 4 days, 1 hour, 35 minutes

So it's been up 10 weeks but the power supplies were just turned on < 12
hours ago? I assume that is just random log-spew from the hot-supervisor
taking over, though?
