OK, have it ever worked for you ? can you test it in some other way ?

Hmm, this looks as if interrupts are not delivered to the right channel
or something, does it work if you only attach one drive ?

Yes, and I know of at least a handfull of other ich5 based system that
runs just fine, so I'm a bit puzzled here. And yes I know the software
RAID is not supported, someone needs to find out the where and the format
of the RADI config for that kind of systems, then it can be easily added
to ata-raid...
