Full backtrace below. from a quick look. END_TRANSFER is timing out, most likely. Tracepoints should give better hints. We might have a bug in dwc3_gadget_suspend(). No idea what's really going on. > Another message that looks worry-some is > "[ 61.495313] omap-dwc3 48880000.omap_dwc3_1: runtime PM trying to suspend device but active child" did you implement runtime PM on dwc3-omap.c? Look at dwc3-pci.c for reference. > If I unload gadget, then suspend/resume system then load gadget everything works fine. right, dwc3 UDC will already have been toredown.
