Thanks. I tried building with the driver embedded in the kernel, but the
compile failed with a halt. No crash is apparent, just a halt. It turned
out that this was repeated until I removed the netconsole command during
boot. System appears stable now. I will try tomorrow to embed the
driver, then add netconsole option in the command line.
Wait, what? The *compile* "failed with a halt"? What the heck does
that mean?
Don't know what it means. The compile just happened to be what I was
execution. The system just stopped with no output to screen, dmesg or
journal. With trial an error I discovered that if I eliminated the
netconsole command from the grub2 linux command line, the system
appeared stable again. I put that netconsole command in
/etc/default/grub, so it is sort of a pain to insert and remove it.

As threatened, I rebuilt with the alx driver embedded. I tested this
kernel just to make sure the alx driver still supported standard
Ethernet, which it did. I then add the linux netconsole command and
rebooted. Everything worked well for awhile, but the output remote
output stopped at 11.909 sec, while dmesg has entries up to 12.627 sec,
and later up to 206.453 sec. The last message from dmesg is "work still
pending". Before, at 11.977 sec there was a "No iBFT detected" message.
This is about the time output terminated. I do not know what iBFT is.
The netconsole on the receiver, nc -u -l 64001, is still running at 100%
cpu utilization.
Journal ctrl on the source gave:

Is the forcing it correct?
