Interesting.  It seems to have worked for me (if I remember) try
applying the attached patch and see if that makes things better - it
tries to nuke pending interrupts when the ehci driver takes control of
the device.

That's odd - I have not done any bulk transfers over usb yet.

Your issue with the nfe is strange too - both my nfe interfaces work
fine, quite a few times I have transferred ~300Mb files between my
laptop and my main machine connected with a crossover cable.  I have
never seen wire speed but the transfer rate is quite respectable - in
the region of 500 - 600 Mbit/s

One thought, what is the revision of your bios?  I am running v1.04 at
the moment.  I found that v1.05 caused a non-acpi kernel to hang and
the acpi kernel would still crash at the same place.  Now that I can
boot an acpi kernel I may just update the bios to the latest.
