Thanks. Full computer name: HP Stream 13, HP 13-c000nd-N2840 aka HP 13-c000nd. There is no sticker on the computer, but an imprint saying "Model 13-c000nd". Is that enough information?
There is no Memtest86+ in the Grub boot menu and I can't add it, so I ran Memtst86+ (V6.0.0 Free) from a USB stick. It has been running now for 32 minutes, and it's at "Pass: 2 / 4" without errors. I guess the rest of the test will take one or two hours. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1440419 Title: Memory corruption detected in low memory Status in linux package in Ubuntu: Incomplete Bug description: The below logging is shown in dmesg.
