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. > If you upgrade to 7.1 -BETA2 you'll also get SATA support for > the IXP card. With 7.0 it will work as ATA 33 in compatibility mode. 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. > I hope this helps you. Absolutely, cheers mate.
