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. I do not trust v5.01 to give reliable results any more. -- 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
