PM866 4104 irq err
One customer had a sudden shutdown in different ocassions, i attached the log file after the error.
I found firmware mismatch with the system and fixed.
What else could be the problem of such cas.
Please search solutionsbank for document:
AC 800M Controller Firmware 5.0.2/0 - 5.0.2/2, Controller Shutdown due to IRQ
I looks like you have that problem and you will need to upgrade to Rev C or later (I would recomment to go to the latest availlable revision)
