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

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. Lenovo support should visit me soon to fix the problem (with new hardware), I'll give an update after that. -- You

I'm starting to think it isn't a software issue. I tried to solve it again because it was becoming impossible to work, and decided to install Ubuntu MATE 16.4.3 LTS (kernel 4.10.0-42-generic) because I read some people had less problems with NVMe drives on that. The problem persisted however. I

I tried it and it worked for 1 day, but it just happened again. Maybe this isn't a problem with Ubuntu/Linux after all? I have already checked the physical connection of the drive and as far as I could find out the drive itself is healthy too, so I have no idea what the problem might be... Any

No, it just had the best result out of everything I have tried. It still hangs occasionally, especially after a cold boot. The kernel from #13 is comparable so far: ~2 hangups per day, mostly after cold boot. -- You received this bug notification because you are a member of Kernel Packages,

No problem, I am very grateful for your help! As I said in the "What have I tried"-section (sorry if it got lost in all the info, I tried to give as much as possible), yes I have tried that and yes I have the same problem. It seems to be worse actually when I put 0 as latency. -- You received

Well... Seconds after my previous message it happened again. So it seems the upstream kernel does not fix the problem. I'm adding GRUB_CMDLINE_LINUX_DEFAULT="nvme_core.default_ps_max_latency_us=250" again. ** Tags added: kernel-bug-exists-upstream ** Changed in: linux (Ubuntu) Status:

@ #3: I installed the latest upstream kernel and will report back with the results. uname -r 4.15.0-041500rc3-generic I assumed it would also make the most sense to remove the GRUB_CMDLINE_LINUX_DEFAULT="nvme_core.default_ps_max_latency_us=250" parameter to see if the upstream kernel fixes the
