We are running ICS ( L27.IS.2.P2).
In 2 or 3 Units of every 500, the ducati reboots again and again due to watchdog timeout. Resetting the device does not seems to be helping. Power cycle sometimes recovers the ducati from rebooting again and again. Even the ducati-m3.bin built using the TI sources also behaving the same way.
Even after disabling the ducati from reloading automatically, we do not see any useful information from the trace1_last.
dmesg shows ducati reboots again and again.
