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.
Below is the console output with stack trace:
stray irq 7

This seems to indicate something in the USB code is re-using a
free()ed memory buffer. Unfortunately, I don't have this particular
hardware available to me, and I don't know how much debugging support
the individual at Transmeta will be able to offer. (He has his own
problems.) Hopefully this will at least help spur some investigation.
