OK. It seems I missed something when doing cleanup. Your patch is working, but only after startup.
When you disconnect modem from usb we have old cids saved. Then we connect modems back, modems won't bring up automatically (and I suppose they souldn't). And when we try to bring interface up we are falling into situation with locked up uqmi: 4912 root 1000 S uqmi -s -d /dev/cdc-wdm0 --set-client-id wds 2 --stop-network 0xffffffff --autoconnect 4980 root 1000 S uqmi -s -d /dev/cdc-wdm0 --get-pin-status 5020 root 1000 S uqmi -s -d /dev/cdc-wdm1 --set-client-id wds 2 --stop-network 0xffffffff --autoconnect 5090 root 992 S uqmi -s -d /dev/cdc-wdm1 --get-pin-status If we now kill all this uqmi processes, we then bring interfaces up :( Maybe it's all because of saved cids? Other case, when only modem's usb data lines are disconnected, without loosing power. This case we don't have locked up uqmi and manual 'ifup $iface' works. Saved cids released successfully. _______________________________________________ Lede-dev mailing list Lede-dev@lists.infradead.org http://lists.infradead.org/mailman/listinfo/lede-dev
