Catalyst 2960s 152-2.E8.bin Stack reboot loop

Just to document this issue I saw while upgrading a 4 switch stack to 15.2(2)E8 

file c2960s-universalk9-mz.152-2.E8.bin

 

1 switch in the stack was stuck in boot loop

error during boot was the following:

 

Unexpected exception to CPUvector 2000, PC =

 

This was resolved by moving to IOS

15.0.2-SE11 MD (c2960s-universalk9-mz.150-2.SE11.bin)

 

I think this is poor from Cisco releasing an IOS with such an obvious troublesome issue.

Post the complete output to the command "dir".  I want to see if I can find the crashinfo.

The crash info was in the flash and passed to Cisco TAC.
