I was recently contacted by an individual at Transmeta who was trying to use FreeBSD current with a board containing an EHCI USB controller and encountered some problems with it. He original intent was to use FreeBSD's USB 2.0 support and the if_axe driver to help debug a problem with said hardware combination with another OS which shall remain nameless. Along the way, he discovered the following: - The USB_ATTACH() routine in if_axe.c would lead to a panic because uaa->iface was NULL. I consider this a bit peculiar because a) with my own test setup (my laptop, with UHCI controller), uaa->iface is always populated, and b) uaa->iface is set to something during the USB_PROBE() routine (it must be, otherwise the probe would fail). I worked around this by grabbing the interface handle using usbd_device2interface_handle(), but having the EHCI driver behave inconsistently with respect to the UHCI and OHCI driver seems a bit counterintuitive. - The system panics under load. In this case, the load was induced by running bonnie on an NFS filesystem mount over the axe0 interface.
