Tony, Thanks. Unfortunately, I do not know the OEM version.  This does sound like what they are describing. Mario

Hi Mario, What OEM version are they using? If it's 40.211 then this is a new way of handling fatal ARM9 errors and you need to start checking the RT logs to see why they are being caused. From the release notes: Upon an occurrence of a main processor – ARM11 or modem processor – ARM9 Fatal error, the device will auto recover by performing a cold boot.  Previously, the device would halt upon an occurrence of this type of error and the device would appear non-responsive with no LED's lit, requiring user intervention to perform a cold boot to restart the unit.  The following registry key controls this behavior:  [HKEY_LOCAL_MACHINE\Software\Motorola\AutoReboot] “Enable” = DWORD: 00000001 Regrads, Tony
