I use Fedora Core 3. I want to start my system in runlevel 3, to log
in text mode, but it is impossible because in the screen I have all
the time the following logs:

hub 1-0:1.0: over-current change on port 1
hub 1-0:1.0: over-current change on port 2
hub 1-0:1.0: over-current change on port 1
hub 1-0:1.0: over-current change on port 2
....

Without stopping. I have two ethernet cards in this machine one
connected to a hub, but I don't know why do appear these messages
related with that hub if this is the case.

I tried to disable those messages using syslog, this is my
/etc/syslog.conf:

#kern.* /dev/console
#kern.warn
/var/log/firewall
# Log anything (except mail) of level info or higher.
# Don't log private authentication messages!
*.info;mail.none;authpriv.none;cron.none
/var/log/messages

# The authpriv file has restricted access.
authpriv.*
/var/log/secure

# Log all the mail messages in one place.
mail.*
-/var/log/maillog


# Log cron stuff
cron.* /var/log/cron

# Everybody gets emergency messages
#*.emerg *

# Save news errors of level crit and higher in a special file.
uucp,news.crit
/var/log/spooler
# Save boot messages also to boot.log
local7.*
/var/log/boot.log

I have the kern.* and the emergency messages disables, so I don't know
where those logs come from and how to disable them.

Any ideas ?


Thanks!

If you have a system capable of running FC 3, you have a system that can
run X. xterms/eterms/konsoles have many advantages over virtual
consoles, so why not use X?

That message is coming from the USB hub module, not anything to do with
Ethernet. It's informing you over and over again with a level of
KERN_ERR that one of your USB devices has gone from "over current" to
"normal" or vice versa. The fact that it keeps happening over and over
again suggests A) a flaky device on the USB chain B) a software problem
with the USB subsystem C) a hardware problem with the USB ports.

Good question. I haven't used syslog in years (metalog >> syslog) and
don't have any of the man pages for syslog, but you might want to fix
the problem instead of ignoring it. In extremis, you can edit
/usr/src/linux/drivers/usb/hub.c , grep for "over-current change",
switch it from err() to dbg() , recompile the modules, then rmmod
everything USB and modprobe it again. That'd keep the messages from
being displayed. HTH,

I mainly want to use the runlevel 3 because this machine is a gateway
and nobody is working directly with it, so in runlevel 3 it should be
a faster boot, but then because of this messages is impossible to use
it at all.

So let's try to solve it !, I have to admit I have no idea on how to
start :-), I have two USB ports in that machine, and in one there is
the mouse plugged, it works perfectly, the other port is empty, so I
think there is no hardware problem there. Maybe is then a problem with
the USB subsystem, but any idea on how to start trying to solve it ?

Thanks !
