Beagleboardxm uses a usb based usbnet ethernet adapter. I use it to mount an
nfs root for some alsa-kernel development. 

I was trying to go to the latest in linux-next. I found tag v2.6.39-rc1
did not work while v2.6.38 did (doing nfs rootfs). I would like to know
if this is already fixed and what patch to use. If you need more info,
I'll try.

I did a git bisect (about 12 rebuilds and boot tries) and:

Gracie:~/buildroot/linux-next$ git bisect good
9e64bb1e9f0613093b3e34ac5402fcfef0dcc35a is the first bad commit

    arm: omap: usb: Invoke usbhs core device initialization

    The usbhs intialization is invoked by all omap3 and omap4
    variant board files.
