I found out that I'm able to 'force' the interrupt storm by provoking
higher disk I/O. Just let dd write to a file in a loop for some hours
and watch vmstat:
while true; do dd if=/dev/zero of=BLA bs=1M count=1000; done
First you'll see that the throughput will decrease, and a few
hours later you'll have /var/log/messages / dmesg full of
interrupt storm messages.

Wow! That's good to hear as well. I'll definitely switch to
-STABLE or 7.1-PRERELASE sooner or later. I'll just give it a try
on my other machines at first.

Absolutely, cheers mate. I owe you one!
