Grub2 BADRAM format for single bad bit
by LinuxOnly from LinuxQuestions.org on (#55BGR)
I'm booting from UEFI and the memtest86+ that came with the distribution is not detected by grub. I had to download the free version 8.4 from Passmark (memtest86.com) and it does not have the option to output results in a GRUB_BADRAM-compatible format. It found a single stuck-at-0 bit in my 16GB of RAM but now what, can anybody help me please?
All I have from memtest is the address: 0x185DDCEEC, and the Grub manual has no details at all about what to do. I run Grub2.04, came with kubuntu-20.04-desktop-amd64. I tentatively put this in /etc/default/grub:code]GRUB_BADRAM="0x185DDCEC0,0xFFFFFFF80"[/code]thinking that should mask one 64b word around the bad spot but I want to make sure before I run update-grub. Or do I have to mask a whole "page" and how much is that?
