[Bug 1876157] Re: memtest86+ hang on GA-P35-DS3R with X5470 and 6 GB

[Sebastian Schleitzer]

memtest86+ 5.01 integrated in xubuntu 20.04 is crashing. It crashs at
30% (16GB) in the first test, after ~5s running. It is completely
frozen.

I tried three PCs (all PCs: lagacy-boot, NO UEFI)

1.PC: memtest freeze , Desktop xubuntu 20.04 i7-2600, 16GB (4x4GB)

2.PC: memtest freeze , Thinkpad xubuntu 20.04 Thinkpad T520, i7-2670QM,
16GB (2x8GB)

3.PC: memtest is running fine: Thinkpad x220, xubuntu 18.04 i5-2520M 8GB (2x4GB)
I upgraded 3.PC to 20.04 - now memtest is also frozen at 60% (picture in attachment)

Title:
  memtest86+ hang on GA-P35-DS3R with X5470 and 6 GB

Status in memtest86+ package in Ubuntu:
  Confirmed

Bug description:
  Yesterday I booted into Ubuntu's memtest86+. I wasn't experiencing or
  expecting problems, and only wanted to make sure memory is okay after
  I had to remove modules to take the PSU out and put it back in. 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).
