I get a kernel panic. Similar to

I do not have a recent write down.

I am using a USCC card, which I have been suspecting before. But it
seems to be related to either netrom/node disconnects possibly with
outstanding frames or tcp/ip started from node, or an DISC/UA at the
ax.25 link layer.

I have seen the DISC/UA in listen on a frozen vnc screen before (vnc)
tcp retried out and the screen wanished.

Nothing in the logs of the failure, except

Oct 16 21:55:27 pc2 node[650]: sm6tpn @ 213.x.x.x logged in
Oct 16 21:55:45 pc2 node[650]: Connected to VAXJO:SK7HW-5
Oct 17 01:47:21 pc2 syslogd 1.4-0: restart.

suggesting node involved, probably sm6tpn issued a netrom connect.
