Yes, this fixes the hang after and MCE, and it shows the error log on the screen.

Great, thanks for testing. Note that in general a bug report shouldn't be resolved before the fix is applied or at least submitted, but anyway I've submitted it now.

Any, clues how to debug this MCE error?

Unfortunately not.
