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.
greg k-h mentioned on the linux-usb list that this might be a 64bit IRQ routing
issue thus here the post.
