[Qemu-devel] Re: ata devices on emulated amd64 on qemu

[Jung-uk Kim]

Okay.  I finally found a fix.  It was actually quite simple.  Newer 
FreeBSD and Linux ATA drivers check whether the PCI ATA controller is 
in legacy ATA mode (aka PATA mode).  The test failed and it was 
treated like a SATA controller.  Of course, IRQ failed to map. ;-)  
Try the attached patch.  Tested with FreeBSD/amd64 6.0-BETA1 guest on 
FreeBSD/amd64 host.

Cheers,
