Hello,

I am getting these kernel messages on the consoles which I want to avoid
as many times I have to login through them as the system runs in level
3.

I have edited the /etc/syslog.conf as:

#kern.*               /dev/console
kern.*                /var/log/kern_messages
# Everybody gets emergency messages
#*.emerg              *
*.emerg               /var/log/kern_messages

Still the messages are getting splashed on to the ttys.
The messages are:
----------------------------------------------------------------
Jul 27 04:04:55 smcindiaonline kernel: EDAC MC0: CE - no information
available: e7xxx CE log register overflow
Jul 27 04:04:56 smcindiaonline kernel: EDAC MC0: CE page 0x7e9eb, offset
0x0, grain 4096, syndrome 0x8304, row 2,channel 1, label "": e7xxx CE
----------------------------------------------------------------

What other tweaks need to done to avoid these?


You could replace the memory that is generating the errors, this error is indicating that your memory is having severe errors.

Or you could just rmmod the edac modules since you are ignoring the errors.

There are a number of things in /sys/module/edac_core/parameters/ the most important being edac_mc_log_ce which would turn things off without rmmod'ing the module, but if one is ignoring the errors, the you might as well turn off the module.

From the man pages it is not clear to me if syslog actually handles the internal kernel messages going to the console, there is also klogd, and I know internal messages still make it to the console even when userspace is screwed up badly, so I would suspect that the klogd thread in the kernel is handling it.
