reboot loop equallogic 4100

Hi, We have a dell EqualLogic ps4100 storage array with a firmware version of, I believe, 7.0.0 and Bootloader Version 3.6.4. It has been purchased a few years back and we no longer have an active support plan. It is now in a reboot loop saying "ERROR:15.4.3:NVRAM contains valid data. This is a WATCHDOG RECOVERY due to the watchdog on a NetBSD processor." I looked around and found out that firmware version 7.0.x have a bug that will result in this issue after 200+ days of uptime. The solution suggested is to update the firmware (which we cannot do because we no longer have a support plan). Is there another way to fix this without resetting the array?
