I have this problem with my motherboard Gigabye GA-990XA-UD3 Rev. 3.0 on
AMD 990 / AMD SB 950. Installed BIOS are latest release (UD ver). USB
2.0 does not work (and RTL8111 also no worked). Problem is analogous as

@rushack: if the problem truly is the same as this issue tracks then the
only solution is to turn off the IOMMU feature of your BIOS settings.
unfortunately this means that any software that relies on IOMMU (mostly
KVM or Xen) will fail to provide the features it supplies.
IOMMU is mainly used to
rushack, the Status of this report is Invalid, as a BIOS update addressed the
original reporter's (Gustavo) issue. Hence, this report is considered closed,
and the scope isn't to you, your hardware, or your problem. So your hardware
and problem may be tracked, could you please file a new report
I had this issue with an GA-970A-D3P motherboard, chipset is AMD 970/AMD
SB 950.
I set IOMMU controller = Enable on BIOS, now I can boot from my USB
stick with no problems...

For people who have the same issue. The bug is resolved on MSI cards too
(at least on MSI 990XA-GD55) with the latest BIOS. This also resolve the
bug with the network card, but does not resolve the bug with low
frequency RAM.

Gustavo, this bug was reported a while ago and there hasn't been any
activity in it recently. We were wondering if this is still an issue? If
so, could you please test for this with the latest development release
of Ubuntu? ISO CD images are available from

I can confirm the bug with the ASUS Formula V and Ubuntu 12.04, amd64
kernel 3.2.0-27. Upgrading the BIOS to 1503 solved the issue for me.
Asus indicates that the BIOS improves USB compatibility.
Note that upgrading the BIOS will require you to re-install grub-efi
because NVRAM is erased.

Ralf-Pete suggests an updated BIOS for his mainboard. I saw that MSI had
also released a new BIOS (for my particular board), so I dutifuly
updated. Unfortunately, this latest (version 1.50) BIOS for the MSI
970A-G46 Mainboard doesn't fix the issue with this board.

This issue also affects MSI's 970A-G46 mainboard with a bulldozer 8-core
cpu. On this system the Realtek RTL8111/RTL8168B NIC is also
unresponsive along with the USB devices. Luckily I have a PS2 keyboard
and was thus able to dig around the booted system a bit using the CLI.
dmesg did not report
The new Crosshair V BIOS (1102) resolved the issue for me.

Hello all.
I don't know if it helps people working on this stuff, but I just bought a
brand new MSI 990FXA-GD65 and a Phenom II X6 with 12GB RAM.
I tried to install Ubuntu 11.04 (x86_64) and it can't find USB devices. I gives
the well known errors (unable to enumerate device, device descriptor
Debian 6.0.3 can't use EHCI_HCD either. If one tries to install it from
an external USB CD-Drive will find that as soon as Debian starts looking
for devices, the drive (used to boot it) vanishes and can't be found.
An upgrade to Testing didn't resolve.
An upgrade to SID didn't solve.

Reproduced with Debian squeeze on a 3.1.0-1-amd64 kernel.

I can conform this bug with both Ubuntu 11.04 and Ubuntu 11.10 (upgraded
from 11.04) and I can also confirm that setting this IOMMU setting to
disabled instead of 64 in BIOS does workaround the issue
