A while ago I wrote this list with the below quoted message. I was
referred to the linux-acpi list and after submitting some information on
request by Bjorn there has been no solution since. Just before the
bugzilla died, I did submit a ticket there, but it seems the bugzilla
won't be back for time to come.
Meanwhile I found that Tomi Orava had also some issue with USB on the
same motherboard [1], but actually got it working just fine. I am not
sure if he was running 64bit or an 32bit kernel but did notice a comment
about the r8169 module requiring use_dac=1, which is the same issue I
have, but only on the 64bit kernel.
Is there meanwhile anything else I can look at. I've become somewhat
used of having no USB on my PC for all this time, but do start to miss
it at times.
P.S. linux-acpi list didn't think that there was a routing issue with
IRQ's, or at least that's how I understood it.
Thanks for your time and help,
oliver

This summer I've purchased a new motherboard, the Asus M5A97 running an
AMD Phenom(tm) II X6 1090T Processor.
The moment I've received this board, I took my trusted Ubuntu 32bit
bootable USB stick (11.04) and loaded up to test if everything was
working. There appeared to be no problems so I continued for a few weeks.
As time went on, I decided it was an idea to install a 64bit OS and
booted the system using a 64bit version of Ubuntu on a USB stick (also
11.04). The system booted extremly slow with any USB devices connected.
Reading up on several lists I've tried all tricks to disable USB 2 and 3
support as that may cause issues, to no avail. So I went back to the
32bit install and stayed there for a while.
Back home from my vacation I installed my favorite distro, Gentoo and
used a 64bit variant. After spending some time setting up the system I
found I had the exact same USB issues. I disabled USB 2 and 3 in the
kernel and built with USB1.1 only to still see the same errors when
connecting anything over USB. Booting works fine, if nothing is
connected. I've searched far and low but have not found anything that
solved or related much to my errors, since everything appears to be
working just fine when switching back to 32bit mode.
Thanks for your time reading this and any thoughts Idea's and pointers.
This really looks like an interrupt routing issue for your hardware and
a 64bit kernel. Nothing the USB developers can do about this, sorry.
Try contacting the acpi developers by filing a bug at
bugzilla.kernel.org and they can work on this.
thanks,
