> xhci_hcd 0000:12:00.0: ERROR Transfer event TRB DMA ptr not part of > current TD This seems to happen if the hardware rejects a TRB with status TRB_ERROR (5). In this case the 'address' field is that of the broken TRB not that of some dma buffer. While the TRB_ERROR status shouldn't happen, the driver doesn't really even attempt to do the correct recovery.
