Comment 25 for bug 1876157

Also encountering this same issue on ubuntu 20.04.2 with HP zbook 17 G2. Memtest loaded through grub freezes. I thought this was because my hardware was faulty. I nearly returned it under warranty.

But downloading memtest86+ 5.01 from memtest.org and loading via syslinux worked fine, and memtest reached 100%. I thought it might be a GRUB issue but copying /boot/memtest86+.bin to my USB drive and loading via syslinux caused the same freeze. So the problem is with the ubuntu build of memtest86+.

Memtest86+ is supposed to "completely reliable", according to their website. A diagnostic tool is near useless if it gives false positives, and a freeze of memtest86+ would seem to indicate a severe memory failure. Including this build in ubuntu is doing a disservice to upstream and to users.
