Default Re: Mysterious server lockups with Ubuntu Hardy

I was able to insmod netconsole.

root@server:~# modprobe netconsole netconsole="1941@10.1.xxx.xxx/eth0,1941@192.168.xxx.xxx/00:14:xx:xx:xx:xx"

mypc:myusername:~ ==>nc -u -l 1941

However, I did not receive any kernel messages on the target machine.

That's despite having generated some kernel messages by inserting a
superfluous module and verifying that with dmesg.
