 - is there any chance booting with noapic would make a difference? I
must say my apic is a bit flaky (according to the logs)

BTW I tried noapic, it did seem to work for two days, but then again
crashed with the same problem :-(

I have played around a little more and found these interesting results.

 - The difference between having or having not the stuck interrupt seems
to be the forced cooling of the attached harddisks; I find this also
very hard to believe, but it is very reproducable; so to anyone having
problems with the promise sata controllers I'd recommend buying
dedicated harddisk coolers.
 - I did a test run with disabling of "stuck" interrupts disabled and I
can say: the interrupt is really stuck, it's no kernel bug; after some
time I rebooted and the controller (or harddisk) still was in a confused
state (no booting possible at all), only after an hour it started
working again; indeed looks like a heat problem.
