Again - a matter of a trade-off, a good compromise must be agreed by all

Right, and logging hw errors from a panic notifier feels simply weird.

x86 has its own, special notifier exactly for that and it is independent
from the panic path but it gets run right after the exception raised due
to the hw error is done.

Dunno if ARM has such facilities tho...

Yeah, MCE stuff right? Not sure for ARM and other architectures as well.
