I already had a bug,
[Firmware Bug]: No firmware reserved region can cover this RMRR [0x0000000078800000-0x000000007affffff], contact BIOS vendor for fixes
After the latest grub and kernel update, I started receiving this as well,
[Firmware Bug]: Your BIOS is broken; bad RMRR [0x0000000078800000-0x000000007affffff]
I'm not sure if this was grub or kernel (possibly kernel) that started this issue. I am perfectly able to boot and run everything, I'm just unsure if this will cause any other issues or if there is a fix to this. I use Asus ROG laptop, specifically GL552VW and have contacted them with this bug but haven't received any response yet.
