mcelog doesn't detect edac_mce_amd #57

Open jollyrogers88 opened 7 years ago

jollyrogers88 commented 7 years ago

I have an AMD Ryzen CPU. mcelog doesn't detect edac_mce_amd, despite it's loaded.

mcelog: ERROR: AMD Processor family 23: mcelog does not support this processor.  Please use the edac_mce_amd module instead.
CPU is unsupported

lsmod |grep edac_mce_amd edac_mce_amd 28672 0

As far as I understand it, instead means that mcelog does not support that processor in question at all.

This is supported by the list of supported processors at the end of the help output.

$ mcelog --help

Also see the FAQ entry How does mcelog compare to EDAC?.

The main advantage of EDAC over mcelog is that EDAC supports reporting memory errors on older systems with separate memory controller. mcelog only works on modern systems where the memory controller is integrated. In addition EDAC works on newer AMD systems.

Please close this issue, if that answers your questions.
