FWIW, I'm seeing the same symptoms on an HP DL320 G3 server. When USB is
enabled, the machine locks up frequently on network I/O (even when no
USB-device is connected).

This still happens on xen 2.0.7. With USB disabled, the machine is indeed
rock-solid.  I'm perfectly happy with that as I don't need to connect
USB-devices, but if you need feedback regarding possible fixes, I'll be glad to
help.

Ingo.
