Install is 100% stock, off Minimal Install disk, then added groups for 
Desktop.  Up to date.

    [tmiller at office04]$uname -r
    2.6.32-279.14.1.el6.x86_64

Then I tried the command the web page has (I see my error during bootup)

    [root at office04 Documents]# /etc/init.d/mcelogd start
    [root at office04 Documents]# /etc/init.d/mcelogd status
    Checking for mcelog
    mcelog is stopped

    [tmiller at office04]$ls /dev/mc*
    /dev/mcelog

so the device does exist

    [root at office04 Documents]# locate edac_mci_amd

returned nothing, but I don't know if it should or not.

I was reading the MAN page, and noticed "See  mcelog  --help for  a list of 
valid CPUs." so I tried it, and it lists:
    Valid CPUs: generic p6old core2 k8 p4 dunnington xeon74xx xeon7400
    xeon5500 xeon5200 xeon5000 xeon5100 xeon3100 xeon3200 core_i7 core_i5
    core_i3 nehalem westmere xeon71xx xeon7100 tulsa intel xeon75xx
    xeon7500 xeon7200 xeon7100 sandybridge sandybridge-ep
All the CPUs I recognize in there are Intel, though I don't know all the 
nicknames.

    cat /proc/cpuinfo

on my system shows (only first of two cores copied)

    processor	: 0
    vendor_id	: AuthenticAMD
    cpu family	: 15
    model		: 35

Not the latest and greatest, and old enough I expected it to be supported 
by now.

Any clues in all this?
