Hi list,
On the linux-usb mailinglist Greg said that I may have an ACPI interrupt
routing issue and should try linux-acpi.
I've created a bugzilla entry[1] with all required files I think are needed?
I'll try to extract the dsdt later and see if it has any compiler bugs
and attach that later to the mentioned bug report. Also I will try
acpi=noirq and see if that enables basic IRQ/USB support. In the
meantime, anybody have any other thoughts as to what I can try?
Thanks,
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,
greg k-h
