To investigate the "L2 watchdog timeout hard reset" system panic and the related FIFO message in the SP log, the most useful FIFO message would be:

C. before Reset BBSP:C=00 L=00 FIFO:

This FIFO message indicates the state of the system just before the reset occurred, which is crucial for understanding the conditions that led to the watchdog timeout and subsequent hard reset.
