I got this message too. I was running pppd 2.3b3 under Linux 2.1.25 with
Alan Cox' patches, and my modem hung up (call waiting). A minute and a
half later, the message appeared on the console that syslog feeds, but it
didn't make it onto disk. I got the same message whenever I tried to
start a new program after that, and couldn't reboot cleanly.

Put in /etc/conf.modules:

alias net-pf-3 off #ax25
alias net-pf-4 off #ipx
