Do you have other USB3 devices to test? Do all the USB devices show the
same symptom when connected to USB3.0 ports?
Also, please try BIOS version 0813 and 0902.
Thanks,

Andiry,
I have tried all the BIOS versions suggested with no luck. I have looked at
all my USB devices and I have currently only the one USB3 device.
I do have a USB3 card in another machine (a Windows XP machine). The USB3
drive works correctly when used on this interface in this machine.
Thanks for the test. Do your USB1.1/2.0 devices work OK on USB3 ports of
M5A97 platform?
Can you plug your USB3 card on M5A97 and try with USB3 drive? If it
works fine, I suspect it's controller HW issue.
Thanks,
Andiry
Andiry,
With a USB2 1Tbyte Harddive in the M5A97 USB3 ports I get the following
dmesg output on linux 3.2.8:

However on linux 3.3.0-rc5 I do not get the warnings:

In both instances I can mount the file system on the disk and transfer
data without error. The dmesg was filtered on "xhci_hcd".
I will now add in the USB3 pci-e card and repeat the test for both USB3
and USB2 harddrives.
