I have the same issue, downgrade to grub 2.00.5043-2 is ok.

Downgraded to the previous version - 2.00.5086-1 - and the error is gone...

Okay, it seems to be this

GRUB_DISABLE_SUBMENU=y
worked for me

I am still getting a bunch of
/proc/devices: No entry for device-mapper found
when running grub-mkconfig, but the grub.cfg file is being generated normally as no 'error' occurs.

I only got those "/proc/devices: No entry for device-mapper found" when I mkconfig before a reboot
After that only the "out of memory" and "syntax error"
And "GRUB_DISABLE_SUBMENU=y" works for me too

Just "modprobe dm-mod" before running grub-mkconfig. In some systems, grub-probe complains about device-mapper and in some it does not. This error is random and not fatal.

occuring again

What occurs again? The syntax error or the warning about no entry for device-mapper found in /proc/devices?
Is this still valid at all?

Is this still valid?
