By "hang", do you mean that no I/O happens for 30 seconds or some other time before these messages show up? BTW, if you run (as root) echo 'func handle_tx_event +p' >/proc/dynamic_debug/control do you see anything new appear in dmesg at this time? That would point to some "action" at xHCI layer, though I suppose it's also possible that nothing interesting happens and the device simply never respo= nds to some commands under some circumstances. --=20 You may reply to this email to add a comment.
