First of all:
I can NOT reproduce the error with kernel 2.6.0-test5.

I have the Zaurus in the craddle all the time. I'm running openzaurus 0.9 on
it.
After having set up usb0 and press the suspend button on zaurus the usb
device gets unregistered as expected. usb0 is not there anymore.
Then I press the button on the zaurus again and the device gets registered as
expected. As usb0 has forgotten about it's IP I do again
#ifconfig usb0 192.168.104.2
and if I want to ping or make something else via usb0 the oops appears.
This is what I got out of ksymoops:

------------------------
Something is still wrong there because once befor there was not uhci but
usbnet . I have no clue why.

2.6 works perfectly as statet above.
Unfortunately I have no time left today so I will not go on before tomorrow.
