USB: hub.c loops forever on resume from ram due to bluetooth Okay, found it. The root cause here was a missing CONFIG_USB_SUSPEND=y, which means the hci_usb device never got marked as USB_STATE_SUSPENDED, which then caused the loop to go on forever. The system works fine now with CONFIG_USB_SUSPEND=y in the .config. Here's the patch to prevent future lockups for this or other causes. I no longer need it, but it does still seem a good idea.
