You're running v3.18 on dwc3 ? How about trying v4.1 ? In any case, v3.18 already had tracepoints support, please enable tracepoints, capture traces and send them along. A single message is not enough to judge what's happening. Also, if you're stuck on v3.18, you really need to ask for support from whoever gave you such an old kernel. My suggestion would be to fire up one of your HAPS platforms configured as a PCIe card, then run v4.1 in any desktop with dwc3 built as a module and try that out. good luck -- balbi
