看systemd的日志，是cpu不支持mce相关的feature，请@GuanJun帮忙确认一下
在mcelog代码mcelog.c if (seen == ALL) { if (!strcmp(vendor,"AuthenticAMD")) { if (family == 15) { cputype = CPU_K8; } else if (family >= 16) { Eprintf("ERROR: AMD Processor family %d: mcelog does not support this processor. Please use the edac_mce_amd module instead.\n", family); return 0; } 可以看到 AuthenticAMD型号，CPU family大于等于16都不支持。
已和相关人员确认，不影响发布
