 |

sys-apps/memtest86 (proprietary version) in the official portage tree is obsolete[1], but version >= 7 ebuild is found in bug 660504, written by Ben Kohler, a Gentoo developer. (It's UEFI only.)
The question is: As far as I tried, the binary, memtest86-bin.efi, cannot be booted when it's in ext4; Grub complains "not a valid root device". (Both lvm and non-lvm) Can you verify it? If I am correct, I'll inform Ben. Sorry if I have done something wrong.
# I've stashed it into an EFI partition (virtually FAT), and it worked.
[1] The version in the portage tree, 4.3.7, doesn't support EFI nor DDR4. memtest86+, a GPL fork, is obsolete, too, and it's not developed anymore,
Edit:
@Tony0945: It's wrong ebuild doesn't warn upon emerging 'em; I filed a bug. (Yep, this problem bewildered me several days ago, too. ;)

Ah! So that's why it doesn't work! |

Yeah, this memtest86 is distributed as an EFI executable, it only works if installed in the EFI System Partition. iamben's ebuild only works if the ESP is mounted on /boot. |
