FWIW, in case anyone strands here in the archives: the msg was
truncated. The full post can be found in a new thread:
https://lore.kernel.org/lkml/e0b80506-b3cf-315b-4327-1b988d86031e@googlemail.com/
Sadly it seems the info "With runpm=0, both reboot and poweroff work on
my laptop." didn't bring us much further to a solution. :-/ I don't
really like it, but for regression tracking I'm now putting this on the
back-burner, as a fix is not in sight.
