A bug has been identified in the Watchdog Timer time-out error interrupt callback defined in the target kernels in the imaging layer where the interrupt status is set incorrectly due to incorrect masking of the error event passed by the driver.

As a result, the system may fail to detect related error conditions, allowing actual failures to go undetected and specifically prevent detection of watchdog timer time-out error. This can leave the IP in an unrecovered error state until a manual reset is performed.

Workaround/Fix:

The below fix can be used in the code base to overcome the issue.
