Yes, that is very likely to be the source of my problems. However, the root
cause is still not clear to me. Why would I get an interrupt storm when
geom_stripe tastes the discs when everything else works like a charm?

I have hw.intr_storm_threshold=5000 set in /boot/loader.conf so the storm is
probably pretty "big". I added that setting back in June when, after
installing a second RocketRAID 454 card, I started getting interrupt storms
at boot during device probing. It didn't really help, but ACPI changes at
the beginning of August seems to finally have removed those problems.

Hmm, anything in the last 4 days that could affect this (kernel/userland was
from 4 days ago)? I don't recall seeing any commits that would be relevant.
