SMBIOS/DMI output is unreliable and sometimes wrong:

/etc/cron.hourly/mcelog.cron:

mcelog: Cannot find SMBIOS DMI tables

Thi si not Linux’s fault – complain to your motherboard vendor.

Ho to resolve this mcelog “SMBIOS DMI” error ?

use –no-dmi option for mcelog like this:

/usr/sbin/mcelog –no-dmi –ignorenodev –filter >> /var/log/mcelog

mcelog decodes machine check events (hardware errors) on x86-64 machines running a 64-bit Linux kernel. Mcelog should be run regularly as a cron job on any x86-64 Linux system.
