Checked with arch/x86/kernel/check.c, it says:
/*
* Some BIOSes seem to corrupt the low 64k of memory during events
* like suspend/resume and unplugging an HDMI cable. Reserve all
* remaining free memory in that area and fill it with a distinct
* pattern.
*/
So please check if you have upgraded the BIOS to the latest version, and
you didn't plug/unplug something or did a suspend/resume before this
error occurs.
