Explanation of Issue
In most instances, either the CEM3 bootline has been corrupted and mostly erased, or the bootline fell back into a "testing" state
It is unknown what can cause this particular issue, but may be due to interruptions in the boot process, either through random resets, power issues, or problems during a firmware update. A failing backplane can also contribute to this issue
Another possible cause is a FLASH failure, though this is rare.
