Thanks for the response. What version of memtest did you run and how long did you have to run it? You ended up having a bad stick of ram? Did you have to test each one individually?
I just built this PC a few months ago and after building ran memtest for a whole day without problem but maybe I'll have to try it again. My log mentions amdgpu after the crash each time so it may be a problem with the graphics card or amdgpu driver. There are a few similar bug posts I've found indicating it might be an amdgpu driver issue. Here are a few. https://bugzilla.kernel.org/show_bug.cgi?id=204181 https://bugs.freedesktop.org/show_bug.cgi?id=106194 https://bugs.freedesktop.org/show_bug.cgi?id=111234 ** Bug watch added: Linux Kernel Bug Tracker #204181 https://bugzilla.kernel.org/show_bug.cgi?id=204181 ** Bug watch added: freedesktop.org Bugzilla #106194 https://bugs.freedesktop.org/show_bug.cgi?id=106194 ** Bug watch added: freedesktop.org Bugzilla #111234 https://bugs.freedesktop.org/show_bug.cgi?id=111234 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1827822 Title: kernel null pointer dereference To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1827822/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
