[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

[Matthias Ferdinand]

Installed binary package memtest86+ from Debian Stable
(memtest86+_5.01-3.1_amd64.deb) in the Ubuntu 20.04 installation, that
version runs fine on all my systems where the Focal Fossa version hangs.

No source code changes between these versions, just differences in the
generated grub menu entries and some translations.

Might actually be a toolchain (compiler, linker) issue.

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).
