LE/RPi2 kernel bug

This issue is very weird. I have LE (Krypton beta 5) installed on my RPi2. It runs well when attached to my television in room A. When moving this RPi2 (without any changes) to room B and attaching it to the television there, I am getting a kernel error.

To be more precise: it says “Kernel BUG at 8052e820 [verbose debug info available]. And a bunch of more info.

It does not start, so not sure how to get the debug log.

As said, the issue is very weird. I can take the same device back to room A and it works again. And then yet again to room B and it does not work.

Any thoughts? Thanks in advance!
