[lm-sensors] w83627ehf module floods log file

[Nameserver.ru]

I have noticed the w83627ehf module (with patch to support DHG) floods
/var/log/messages this way:

...
Jan  3 21:54:40 anli w83627ehf 9191-0290: Increasing fan 4 clock divider from 4 to 8
Jan  3 21:54:43 anli w83627ehf 9191-0290: Increasing fan 4 clock divider from 4 to 8
Jan  3 21:54:46 anli w83627ehf 9191-0290: Increasing fan 4 clock divider from 4 to 8
Jan  3 21:54:49 anli w83627ehf 9191-0290: Increasing fan 4 clock divider from 4 to 8

Jan  3 21:59:31 anli w83627ehf 9191-0290: Increasing fan 4 clock divider from 4 to 8
Jan  3 21:59:34 anli w83627ehf 9191-0290: Increasing fan 4 clock divider from 4 to 8
Jan  3 21:59:37 anli w83627ehf 9191-0290: Increasing fan 4 clock divider from 4 to 8
Jan  3 21:59:40 anli w83627ehf 9191-0290: Increasing fan 4 clock divider from 4 to 8
...

You see, every 3 seconds the module generates new message. Is it possible to
suppress this logging?

Hello,

There are several ways to suppress this information in /var/log/messages:

1. Turn kernel driver debugging off:
Device Drivers -> Generic Driver Options -> Driver Core verbose debug messages

Or, if you can't turn that off,
2. Reconfigure syslogd to ignore the messages. This depends on which
distro you are using. Look under /etc/syslog.conf, /etc/syslog.d/*, or
man syslog. The messages are printed at KERN_DEBUG level, and
typically syslogd ignores these messages.

Or, if you can't turn it off,
3. Reconfigure syslogd to send KERN_DEBUG messages to a separate log
file. man syslog.

Hope that helps,
David

Correct, but that being said...

This really suggests that the driver fails to actually increase the fan
clock divider for fan4. This could be a bug in the drivers, worth
investigating. David, care to take a look?

Oh, I didn't notice that. I apologize, I'll look into it and see if I
can discover what's going on.

For the records: this was a real bug, which is fixed now (fixed in
2.6.21).
