Additional info:
Comment 1 Andre Robatino 2004-06-14 18:44:51 UTC 
  I have the same problem using DSL with a clean FC2 install on two
different machines (Microtel SYSMAR561 and Emachines 333cs).  It
persists with the 427 and 435 kernels.
Comment 2 Need Real Name 2004-07-12 21:45:17 UTC 
I get the same thing - but to screen (on shutdown).
Which log are you looking at?
Comment 3 Andre Robatino 2004-07-13 05:26:08 UTC 
  When the xDSL network connection goes down automatically on
shutdown, it only shows on the screen.  However, if you bring the
network connection down manually with Network Device Control without
shutting down, the errors are written to /var/log/messages.
Comment 4 Marek Greško 2004-07-13 07:41:23 UTC 
I found it in /var/log/messages after shutdown not manually bringing
down. Here is corresponding line from syslog.conf:

*.info;mail.none;authpriv.none;cron.none      /var/log/messages
Comment 5 Andre Robatino 2004-07-13 15:38:06 UTC 
  Strange.  I have the same line in syslog.conf, but my errors are
never written to /var/log/messages unless I bring down the connection
manually.
Comment 6 Andre Robatino 2004-08-03 23:42:52 UTC 
  Using kernel-2.6.7-1.494.2.2, the error appears to be gone.  (BTW, I
commented in bug #126190 that it appeared to be a dupe of this bug but
there was no response.)
