fedora kernel 3.9.10-100.fc17.x86_64 xhci_hcd 0000:12:00.0: ERROR Transfer event TRB DMA ptr not part of current TD i got this message about every 200 MICROseconds after a warm boot. unplugging the usb3 cables silenced it. plugging back in, everything came up fine. grepping messages for 0000:12:00.0 shows everything on the usb3 hub; hubs, cameras and network adapters (fyi none of which are really usb3 - all usb2 except the first hub). i can check whatever you like if you want more info but i'm really only reporting the message flood. cheers andrew-- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
