I'm CC-ing Stefan, who ported Linux to this platform.

Applying the patch you suggested did not help. I'm still getting TX unit
hangs. I don't see any netdev watchdog messages. When the hang occurs
I cannot get the prompt, so I cannot run ethtool.

The following command works always

dd if=/dev/zero of=/mnt/test bs=512 count=2

and the following causes Tx unit hang

 dd if=/dev/zero of=/mnt/test bs=512 count=3

Stefan, are you aware of any PCIe related problems on Canyonlands ?
AMCC have compatibility chart on their site, which indicates that this
particular card (Intel PRO/1000 T Desktop Adapter) Iwas tested with
linux-2.6.25 kernel.

What Linux kernel version did you use? From kernel.org or from the 
linux-2.6-denx repository? Please send the complete bootup log including 
U-Boot startup log.

Thanks.

Best regards,
Stefan
