Sorry I didn't explain well in my last email. I try to explain more exactly and more detailed:
These are the modules I load: modprobe 6pack modprobe ax25 modprobe netrom There are 2 axports attach: - sp0 (6pack: kissattach -6 -l /dev/ttyUSB0 sp0 -> TNC2 radio link) - ax0 (axip interface via 44 net: kissattach -m 256 /dev/ptyq1 ax0 ) There is one netrom interface broadcasted both sp0 and ax0.
After a while (1 hours?) from reboot I no longer receive packets (all, both netrom and simple ax25 packet) from interface sp0 despite I can see DCD ON when TNC is listening to beacon of other stations and also to my axcall answer.
All is regular on interface ax0.
The testing conditions are: last Raspbian Stretch, downgrade to kernel 4.1.21 (VE7FET AX25 software suite or base repository (APT) AX25 don't change)
Another testing condition don't have the specific problem of missing listening packets: older setup of Raspbian Stretch with 4.9.59 kernel and only one axport to tnc2, and base (APT) ax25 software suite
Sorry I don't know if it is OT for 44 net mailing list, if not please let me known if there is another more appropriate mailing list
Thanks

I think kernel downgrade to 4.1.21 (or similar) don't solve all issues, net/rom seems works fine but not basic packet: after a while (1 hours?) from reboot, I no longer receive packets from TNC2 AX25 interface, despite I can see DCD ON when TNC is listening to beacon of other stations and also to my axcall answer. The testing conditions are: last Raspbian Stretch, downgrade to kernel 4.1.21 (VE7FET AX25 software suite or base repository (APT) AX25 don't change), vpn to 44 net, 1 axport to serial tnc2 in 6pack mode, and 1 axport axip tunnel - route to another node
I don't know if I've made some mistakes in this trials: it is strange but in another situation (older setup of Raspbian Stretch with 4.9.59 kernel and only one axport to tnc2, and base (APT) ax25 software suite), nothing else, all base ax25 packet works fine and stable.
Suggestions are welcome :)
