Hi Boris, Excellent idea. With CONFIG_DEBUG_OBJECTS_FREE=y I've hit this twice: ODEBUG: free active (active state 0) object type: timer_list hint: xhci_stop_endpoint_command_watchdog+0x0/0x2b0 So I'll try to hunt that down on the xHCI side and report over to linux-usb. Sorry for the unrelated noise on this patch -- my guess is that timing changed just enough for the xHCI driver to hit this. :) -- Joe
