JMicron Raid Problems on a Gigabyte GA-P35-DS3

[Andreas Geringer]

If it is not too much to do for you, I would like to try the patch.

I have another sata-device without raid with the new gentoo-system. So 
it is not really urgent for me.  I think I have also the time to wait 
for the new version.
