I cant suspend/resume at all on my ASUS, it locks up somwhere long before it gets to ATA.

I dont think this is an ATA issue, I think the new acpi/interrupt code is not setting up things as they should on resume. That said I'm interested in getting this to work as well, but so far I dont even make it to ATA during resume... -Søren .. but it works under windows!!
