Comment 32 for bug 209454

I'm running Jaunty, and I still have this issue. The relevant output from lspci -vvnn is:

00:09.0 SATA controller [0106]: nVidia Corporation Device [10de:0584] (rev a2) (prog-if 01)

 Capabilities: <access denied>
 Kernel driver in use: ahci

I can boot up with or without pci=nomsi, but only because I have a PCIe RAID controller that I'm using to run my OS off of. The system will only recognize my SATA drives with pci=nomsi and the drives in AHCI mode, but I'd like to be able to use msi for PCI passthrough with KVM.

I haven't yet tried the Karmic kernel because I've got a very fragile system configuration that doesn't adapt well to change. :)

Is there a fix out there for this?
