[Bug 1876157] Re: Memtest86+ in Ubuntu 20.04 doesn't work, switch to Coreboot branch or package new release v5.31b is available since 12/04/2020

[Mantas Kriaučiūnas]

There is a fork and major rewrite of the Memtest86+: https://github.com/martinwhitaker/pcmemtest
Unlike Memtest86+, PCMemTest can be used with UEFI as well as with legacy BIOS.

I think Ubuntu and Debian should follow Mageia Linux distribution, where
Memtest86 is replaced with PCMemTest, see Release Notes:

https://wiki.mageia.org/en/Mageia_8_Release_Notes#PCMemTest

PCMemTest
This is a fork and major rewrite of the Memtest86+ memory test utility. Unlike Memtest86+, PCMemTest can be used with UEFI as well as with legacy BIOS boot. PCMemTest replaces Memtest86+ as the memory test utility on all the Mageia ISOs. It may also be installed in a user's system.

PCMemTest can be started from GRUB EFI mode like Linux kernel:

menuentry "Memory Test (PCMemTest" {
	search --no-floppy --set=root --file /install/pcmemtest
	set gfxpayload=640x400,800x600,1024x768
	linux 	/install/pcmemtest
}

Bug description:
  Memtest in Ubuntu is very old, not updated since 2013, new Memtest86+
  release v5.31b is available at http://memtest.org , dated 12/04/2020

  *** Enhancements in v5.31b : ***
  I've started compiling many codes branches to release public builds again! Here is Memtest86+ 5.31b, with many bug fixes in the core functions.

  Also there is updated Memtest86+ branch at https://www.coreboot.org/Memtest86%2B - several people told, that this branch does work, where original Memtest 5.01 doesn't, see
  https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=943752

  ---- Original bugreport ----
  I ran it twice, and both times it hung at exactly 79% in the first test. Even fail safe mode hung exactly at that point.

  Then I booted with the floppy image from memtest86+-4.10.floppy.zip
  and it worked fine.

  Today I installed memtest86+_5.01-3ubuntu2_amd64.deb from Ubuntu 19.10
  and that worked fine too.

  The failing version is 5.01-3.1ubuntu1.

  Memory configuration is 2 * 2 GB (F2-6400CL5-2GBPQ) and 2 * 1 GB
  (OCZ2G8001G) working in dual channel mode. CPU is Harpertown Xeon
  X5470 running at stock speed (3.33 GHz).
