Hello,
Yesterday, I applied the latest updates on my Debian7 Wheezy (x64)system
running, including a kernel update. I have a Kantornics TNC in kiss mode
connected to a prolific USB serial adapter, working in single channel mode
(no mkiss).
The result was that my TNC doesn't work properly anymore: Rx works
properly until the first transmission (which happens on the radio
correctly). After that, no more data is received from the TNC - Tx working
correct. After a TNC reset, it works again until the first Tx. I will try
to find the exact cause of this behavior.
I would suspect either an issue in the USB driver, or in the ax.25 stack.
Please exercise caution on this update.

Marius;
I had issues as well but after a reboot and going through syslog errors I
was able to become functional again. You may also want to review dmesg for
warnings.

Knowing the kernel version that you "upgraded" to would also be helpful. I
have noticed a few "system" errors after a recent update but nothing
obvious in dmesg so far. If your system keeps an older kernel installed it
might be worth booting it to rule out the new kernel.

The package is linux-3.2.0-4-amd64 released on debian with version
3.2.65-1+deb7u1.
The interesting part is that it somehow hangs the TNC (Kantronics 9612 in
kiss mode).
I set up a plain ax.25 stack, and on first packet TX, the TNC stops
receiving, no LED activities, nothing.
As if a wring kiss command is sent to it (the bad thing is I don't know
exactly how kiss works...)
The TNC doesn't come out of kiss mode, but stops receiving.
Powering the TNC down and up again restores the functions until the next TX.
Still digging,
Marius, YO2LOJ

Be sure to turn on logging in kissattach and ax25d. They go to syslog. I
think it's a "-l" switch.

Sorry for all the fuss on this topic.
It seems a TNC problem wich just fails to receive after a initial TX.
But better safe then sorry :-)

Just FYI:
A hard reset to factory of the TNC defaults fixed the problem.
The strange thing is I still don't know what happened, it worked untouched
for some 3 years...

The wonderful magical world of tnc's. Check the backup battery, as they
tend to act oddly when it is dead or dying.

Tnx,
Just replaced it since it was the "usual suspect" :-)
