So that's the problem with this approach. Kishon reminded me that on TI parts we see some PM problems because we don't always do a cleanup on the USB side for gadgets. I think the right answer here is to mirror the usb_stop() function in bootm_disable_interrupts() in common/bootm.c for the gadget code as well. -- Tom
