Any attempt to add SATA V2 or FC V2 Bricks from manufacturing to an Ax300, Ax500, or Ax600 at release 04.03.01 thru 04.03.02 will result in repeated Slammer CU panics in the ConMan component leading to CU Failure, and possible Emergency System Shutdown.

The error results in buffer overflow, corrupting ConMan memory structures, typically resulting in SEGV for the dumper.
