CentOS 6.4, 2.6.32-358.11.1.el6.x86_64 (And no, I can't just upgrade - the users have to be sure that the computational results will be correct....) It's throwing ECC errors. Trying to start mcelogd, first it said nothing. Restart told me "Please load edac_mce_amd module." I did a modprobe edac_mce_amd, and lsmod tells me it's in. But now service mcelogd restart Stopping mcelog Starting mcelog daemon [FAILED] AMD Processor family 16: Please load edac_mce_amd module. [FAILED] And in messages, mcelog: CPU is unsupported#012: Success "Success"? Anyone have any ideas what I'm missing; why I've loaded what it says it needs, and it still thinks it needs it? mark
