Comment 190 for bug 1746340

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)

@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?
