For anyone struggling with this hideous bug, try the following: add "nvme_core.default_ps_max_latency_us=250" in /etc/default/grub, for example:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pcie_aspm=off nvme_core.default_ps_max_latency_us=250" then run "update-grub" My laptop has been running smoothly for a week now. (/dev/nvme0n1 S444NY0K600040 SAMSUNG MZVLB256HAHQ-00000 1 81.09 GB / 256.06 GB 512 B + 0 B EXD7101Q) see more infos here: https://wiki.archlinux.org/index.php/Solid_state_drive/NVMe @kernel developers, would it not be great to detect such disks and lower automatically the nvme_core.default_ps_max_latency_us? Thi bug is really hard to detect and solve because there are NO logs whatsoever. Disk goes read-only ya know? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1746340 Title: Samsung SSD corruption (fsck needed) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1746340/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
