[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
This fault also occurs for me with Ubuntu 20.04. I have 3 x 4G sticks. Any single stick in any slot and the Ubuntu-bundled memtest runs fine. More than one stick will result in the Ubuntu-bundled memtest freezing (at exactly the same point each time). The memory is good, as determined by Memtest86+ 5.31b booting from a CD. If developers don't have time to fix it for 20.04, and I realise they are volunteers working in their spare time, then IMHO it would be better to remove it altogether. Otherwise, the faulty version causes people to waste a lot of time thinking they have bad memory, many of them never realising the memory is good and possibly throwing it away. I know it would have saved me a lot of time today if this faulty version hadn't been bundled with 20.04. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1876157 Title: Memtest86+ in Ubuntu 20.04 doesn't work, switch to Coreboot branch or package new release v5.31b is available since 12/04/2020 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/memtest86+/+bug/1876157/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I already know and as already told upstream developer already working contacting developers of these forks for collaborate and try to merge works of all upstream. For now I'll wait progress of this instead wasting time applying, adapt (for 5.31b) and testing patches from forks now, I'll apply them only if there will be important issue that can't wait. I have other projects/packages I contribute to, I only recently became a maintainer of memtest86+ after investing many hours in the last 2 months to update it, fix a lot of problems and make some other improvements. If there are still important issues (with latest version, 5.31b+dfsg-4) let me know please, for now on all cases where old version was not working the latest is on my tests and the only thing not working is the multiboot (which is secondary and disabled by default) which I am not able to fix quickly (I have no knowledge about it) and so I left it like this (after adapting the old patch to at least fix the memory detection) to better invest the time in other parts and projects where I have more knowledge. If anyone wants to contribute a patch that fixes it is welcome and I would apply immediately (after testing if it doesn't cause regressions) and I will do new build. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1876157 Title: Memtest86+ in Ubuntu 20.04 doesn't work, switch to Coreboot branch or package new release v5.31b is available since 12/04/2020 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/memtest86+/+bug/1876157/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Lionel Debroux told at http://bugs.debian.org/943752 Date: Tue, 18 Jan 2022 23:08:44 +0100 https://github.com/anphsw/memtest86 is another memtest86+ fork which contains some interesting changes. Unlike both upstream and coreboot's fork: * in dmi.c, it's not affected by https://bugs.debian.org/1003906 , and it contains updated DMI struct definitions; * in spd.c, struct pci_smbus_controller smbcontrollers[] contains ~30 additional entries for Intel hardware; * in main.c and test.c, it has new latency analysis and Rowhammer tests; * etc. In config.h and lib.c , both forks have support for 4 serial ports, up from 2. On its side, the coreboot fork integrates multiboot changes, embeds a much newer and larger JEDEC ID list than both upstream and anphsw's fork, etc. Lastly, unlike both forks, upstream 5.31b has DDR5 entries in dmi.c's static char *memory_types[], a number of typo fixes, the beginning of a user-space unit test program for memtest86+ (which could be used as a starting point for fuzzing the DMI, SPD, ACPI, etc. parsing functions). It's a mess :) PS: I used the following mechanical changes to clean up a bit the large diffs between memtest86+ 5.31b and the anphsw / coreboot forks: perl -pi -e "s/v->/vv->/g" * perl -pi -e "s/isdigit/mt86_isdigit/g" * perl -pi -e "s/memcmp/mt86_memcmp/g" * perl -pi -e "s/memmove/mt86_memmove/g" * perl -pi -e "s/strncmp/mt86_strncmp/g" * perl -pi -e "s/strstr/mt86_strstr/g" * perl -pi -e "s/strlen/mt86_strlen/g" * perl -pi -e "s/error\(/mt86_error(/g" * perl -pi -e "s/print_mt86_error/print_error/g" * + 1 manual edition to test.h for renaming v to vv Many whitespace changes still appear in those diffs, despite passing the -b or -w flags to `diff`. ** Bug watch added: Debian Bug tracker #1003906 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1003906 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1876157 Title: Memtest86+ in Ubuntu 20.04 doesn't work, switch to Coreboot branch or package new release v5.31b is available since 12/04/2020 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/memtest86+/+bug/1876157/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Here too, memtest86+ 5.01 version from Ubuntu would consistently freeze during test #2 (58% in). If test #2 was skipped, test #3 would trigger a reboot at some point. Those 2 problems only occurred when more than 4G was installed in the system.

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.

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
}

Hi, I am also affected by this problem. It is an overflow check using undefined behavior in an overflow check in test.c that looks like "if (pe + SPINSZ > pe && pe != 0)" but with >4G memory pe + SIINSZ wraps around.

Same problem with HP Elitebook 745 G2, 2x8GB DDR3-1600. memtest from ubuntu 20.04.1 installer (memtest-5.01) freezes after two seconds (first test at 51%). This happers every time.

I have a similar problem. I have Ubuntu Studio 20.04 installed. The included Memtest86+ 5.01 freezes at 55% on test #2 every single time. Memtest86+ 4.20 from an Ubuntu 14.04 DVD passes without error. Memtest86+ 5.31b downloaded and burned to a CD-RW passes without error. I have also encountered the issue where Memtest86+ 5.01 freezes on many machines with SMP activated.

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.

I think it is not the problem of the memtest version 5.01. When I boot memtest 5.01 via USB-Stick it is working. No problems. Only the integrated memtest 5.01 is making problems (started via grub, ubuntu 20.04) memtest 5.01 was also working in ubuntu 18.04 (via grub).

Get memtest into debian, and it will get pulled in to Ubuntu ... eventually. The reason it hasn't been updated is that Ubuntu does not wish to fork memtest from Debian. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1876157 Title: Memtest86+ in Ubuntu 20.04 doesn't work, switch to Coreboot branch or package new release v5.31b is available since 12/04/2020 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/memtest86+/+bug/1876157/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
