Description of problem:
I'm having the problem discussed at this URL,
http://www.ussg.iu.edu/hypermail/linux/kernel/0401.2/0420.html. My
machine is a home built dual PII 333 machine. In a gnome-terminal
window, I get this message repeatedly for both CPUs.

Message from syslogd@dragon at Mon Feb 16 20:24:40 2004 ...
dragon kernel: MCE: The hardware reports a non fatal, correctable
incident occurred on CPU 1.
Message from syslogd@dragon at Mon Feb 16 20:24:40 2004 ...
dragon kernel: Bank 1: a200000000000185

The problem existed for both kernel 2.6.1-1.65smp and 2.6.2-1.81smp,
so it may actually be a problem in syslogd, but they occur less
frequently with kernel 2.6.2-1.81smp, with no change in the syslogd
version (sysklogd-1.4.1-13)

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Boot either kernel listed smp kernel
2. Open gnome-terminal, as root or regular user


Actual Results:  MCE errors reported repeatedly

Expected Results:  No MCE errors should be reported. If there is a
real error being reported, that's fine, but I don't have a clue how to
correct it.

can you attach output of x86info -a please?
Comment 2 Dave Jones 2004-02-17 07:34:30 EST
(make sure it a)runs as root and b) cpuid & msr modules are also loaded)

This appears to have been corrected in kernel-smp-2.6.3-1.91. I used
to see the messages printed quite frequently while updating with
yum/up2date, but I haven't seen them since upgrading the 2.6.3-1.91
(and am currently pulling ~350 updates!)

I've disabled the background checker for now. It raises quite a lot of
false positives, sometimes for reasons completely unknown.
