Yes, I am running a couple of firewall rules that block UDP packets and log
them. But normally they appear in syslog, not on every open console.

Which would explain why my kernel considered these high-priority? Because
they were malformed? As for the second message, does that appear to you
experts to be related to the first? It means nothing to me.

Btw, I should mention that I've had a lot of trouble with misconfigured Win32
machines on mother.com's LAN (mostly cohosting customers' servers) sending
individual packets to 137/udp but this is the worst it's ever been (I had
over 600Mb of logfiles in just twelve hours!). And what I really want to know
was why did my kernel have thhe impertinence to write the logmessages to
every console? It made the machine almost unusable!
