Crash Loop after Shutdown

[Satras]

Hi,

my pfSense was running fine since some time now, till I shut it down last Monday. This was to replace the RAM. When I booted it up it started looping.
Even after a fresh build it sometimes loops (even with the old RAM) with or without my config. I was able to gather the following log:

Not sure what I should do.
The Box runs fine for some time, if I then reboot the box it starts looping… or sometimes even without a reboot the machine restarts and loops.
I'm totally lost.
