Linux AX.25 stack now toxic for connected packet connections with Ubuntu 20.04 / 5.8.0-44-generic #50

Hello Everyone,

I wanted to check with the larger community to see if others are experiencing system crashes when making connected AX.25 sessions.? I have confirmed that this is NOT an RFI thing and sending unconnected (UI) transmissions (beacons) small or large is fine, and even initiating the beginning of connected session to a non-existent remote station callsign is OK with axcall, linpac, etc.? The issue is that once a valid AX.25 connection is established, I begin to receive data from the remote station and then seemingly when my station is to send an ACK packet, the machine locks hard.? No segmentation failure, no kernel panic, the Gnome3 display stays up but the screen no longer updates , nothing in the logs and even stops pinging from a different machine on the LAN.? The machine is 100% crashed and this is 100% reproducible.

Is anyone else seeing this?
