I'm using 

 -device ahci,id=ahci1
 -device ahci,id=ahci2
 -drive id=boot,format=raw,file=/root/boot,cache=writeback,if=none
 -drive id=root,format=raw,file=/home/hurd,cache=writeback,if=none
 -device ide-hd,drive=boot,bus=ahci2.0
 -device ide-hd,drive=root,bus=ahci2.1

(yes, it's an odd setup, that was meant to stress the ahci driver
discovery).

It's the qemu controller, I don't think there is any issue there.
