PB2 Fail Log

See the attached two log files.  One is from a PB2 board that has a Kernel crash when attempting to boot, after downgrading to MPQ r6537 OR 7.4 r6865 firmware.

The second log is from a PA5 board, doing the exact same downgrade.

Notice that the PB2 board will crash, while the PA5 board will 'eventually' recover and boot.
-------------------
IMHO this is another reason to implement bug 12816 and bug 12817.

Upgrading PB1/PB2 units to >r6872 will then put them in a state that they are UNABLE to downgrade firmware, it leaves them in a bad state.  While this maybe a mote point to make, it has the 'potential' to cause problems for us in the future.

I think unless there is a good reason, this is a won't fix. It might actually be hard to fix anyway.
