To add some closure to this ticket: Lenovo support had to visit me 3 times: - first they replaced the SSD -> same problem - then they replaced the SSD adapter and cable -> same problem - lastly they just replaced the whole motherboard -> fixed the problem for Windows So it seems I definitely had a hardware problem. After all the problems I decided not to install Linux anymore, since I discovered you can now run Linux natively on Windows (it's called the Windows Subsystem for Linux or WSL, cool stuff!). So in the end I'm not sure if I ALSO had a software problem, but I'm not gonna risk it by going back to Linux... ** Changed in: linux (Ubuntu) Status: Confirmed => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1737934 Title: Samsung SM961 NVMe SSD randomly unmounts/loses connection/unavailable To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1737934/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Had the same problem in Windows (I think, harder to diagnose on Windows), even after installing updates for BIOS, firmware & drivers, so this is probably a hardware problem.
