All - Tried to upgrade 5 2960s Stacks from IOS 15.0(2a)SE9 to the following IOS -
c2960s-universalk9-mz.152-2.E7.bin
Once we did this we were faced with a continuous switch stack reboot on all 5 stacks with the below error output.
Has anyone experienced this issue? Is this ver. not compatible with the 2960s or could this be a bug in the IOS?
Thanks,

- If it's stack related , then examine this , by breaking the stack and try this on a single box only; check if the problem persists. If so roll back or try another IOS version, more recent or even gold-starred, if possible.

Do not, I repeat, Do not use 15.2.2 E7 on a 2960s. Although it shows available, it will do a continuing boot load on the switch. Only way out of it on a 2960s is to Rommon and Xmodem the previous code. In my case 15.2.2 E5 works fine. On a stack of 4 and production environment, this ended up being a long night!
