Sorry this took so long, but I can confirm that the bug does not reproduce on kernel 4.10.17-041017-generic that you linked to, or on 4.13.0-37-generic from 17.10. Interestingly, kernel 4.10.17 is 3-4x slower at writing to the NVM device than 4.13.0-37, with the former I get 260-290 MB/s, with the latter I get about 1 GB/s.
In any case, the bug is fixed in 4.10.17. -- 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/1700225 Title: Writing to GPT partition on NVM device triggers "Kernel BUG" Status in linux package in Ubuntu: Confirmed Bug description: When I try writing a large amount of data to a GPT partition on my NVM SSD using dd, after a second or so I get "kernel BUG" messages in dmesg, and the writing comes to a halt. The machine remains responsive and I can write to other disks, but if I run "sync", it hangs forever. The bug is 100 % repeatable. To replicate, run: dd if=/dev/zero of=/dev/nvme0n1p1 This happens only when I write more than 0.5-1.5 GiB to a GPT partition on the NVM device. The bug does not happen in the following cases: - writing just 500 MB on a GPT partition - writing to the raw device (/dev/nvme0n1) - writing to a DOS partition (i.e. when the NVM device is using a DOS style partition table) The device in question is a 1 TB Samsung 960 EVO M.2 SSD. Ubuntu release: 17.04 I have dmesg logs available of four instances of this happening, with very similar stack traces. I will be happy to experiment and provide any additional information you may need. --- ApportVersion: 2.20.4-0ubuntu4.1 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC1: jl 1792 F.... pulseaudio /dev/snd/controlC0: jl 1792 F.... pulseaudio CurrentDesktop: Unity:Unity7 DistroRelease: Ubuntu 17.04 IwConfig: lo no wireless extensions. enp0s31f6 no wireless extensions.
