Gerben, as per
http://www.asus.com/Motherboards/SABERTOOTH_990FX/#support_Download_8 an
update is available for your BIOS (1604). If you update to this, does it
change anything?
If not, could you please both specify what happened, and provide the output of
the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date
Thank you for your understanding.

Title:
specific device not available in client (passthrough) with high cpu
load on host, none in client
Status in “linux” package in Ubuntu:
Incomplete
Status in “qemu-kvm” package in Ubuntu:
New
Bug description:
I've got a specific device which is not always handed down to the kvm
client showing a high cpu load on the kvm host. No cpu load shown in
the client (win7).
A few (two) times I saw this device working properly with no high cpu
usage on the kvm host, but this was broken after a reboot of the KVM
host in at least one time. Reboots of the client showed the device
continue to work correctly multiple times before I rebooted the host.
06:00.1 Audio device [0403]: Advanced Micro Devices [AMD] nee ATI
Cedar HDMI Audio [Radeon HD 5400/6300 Series] [1002:aa68]
If the device works correctly, a device is shown by the device manager
within windows 7. If not no device is shown, while the host KVM
process consumes all cpu cycles assigned to it (2 cpu's in this case)
and the client shows not cpu power used.
My guess this is specific to this device (a sound device on the
graphics card, HD5440). The graphics device and an USB device in
passthough both work without problems.
When removing the sound device no high cpu usage is shown on the host.
Adding the sound device again, high cpu usage is shown on the host.
The host is a Quantal server installation.
