Hi Robin,

(And again because I failed to fix the email address after using the
archives mailbox, apologies for that)

I started looking at this issue and managed to reproduce the issue
instantly with

	dd if=/sys/firmware/acpi/tables/data/BERT of=/dev/null bs=7

I've attempted a few ways of fixing it based on the comments on this
thread but wasn't successful so far (my knowledge is pretty limited in
this area too, so not a big surprise). How can I be of assistance to debug/test
patches for this issue?
