SL 6x X86-64 on an AMD CPU. During boot, the dac_mce_amd kernel
module is indicated as not being loaded. However, lsmod as well as
a direct viewing of /proc/modules shows that the module is loaded
and live. Evidence below. Is this consistent? Is the module
actually active?
The module is normally loaded when "edac" service is started (from
edac-utils package). Do you have it enabled at default runlevel?
You can check if all correct modules are loaded with
edac-ctl --status
command.
From man on the machine as installed by SL6x:
EDAC-CTL(8) EDAC admin utility
EDAC-CTL(8)
NAME
edac-ctl - EDAC admin utility
[snip]
--load Load EDAC drivers.
end man.
[root@ahprc4 ykarant]# edac-ctl --status
edac-ctl: drivers not loaded.
[root@ahprc4 ykarant]# edac-ctl --load
Unknown option: load
Usage: edac-ctl [OPTIONS...]
--quiet Quiet operation.
--mainboard Print mainboard vendor and model for this hardware.
--status Print status of EDAC drivers.
--print-labels Print Motherboard DIMM labels to stdout.
--register-labels Load Motherboard DIMM labels into EDAC driver.
--delay=N Delay N seconds before writing DIMM labels.
--labeldb=DB Load label database from file DB.
--help This help message.
Thus, the --load switch documented in man is an unknown option. What
have we incorrectly done?
