Let me know if you want me to put in debugging messages or try for more netconsole output. I built a bunch of kernels last night, but ran out of reboot time (learning git...) to test them.

I'll keep poking at this, though tax time is starting to fill my time right now too. :] John -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
