After disabling APST by adding "nvme_core.default_ps_max_latency_us=0" in /etc/default/grub, the bug went away. Since yesterday, however the bug has returned, with the system dying with I/O errors after an hour or so. I verified, that the kernel option is still being set $ cat /proc/cmdline BOOT_IMAGE=/boot/vmlinuz-4.10.0-22-generic.efi.signed root=UUID=365f1a9c-9598-4ad5-a387-d02f771767a1 ro quiet splash nvme_core.default_ps_max_latency_us=0 vt.handoff=7 however it turns out that it is being ignored for some reason, and running $ sudo nvme get-feature -f 0x0c -H /dev/nvme0 reports that APST is enabled. I can successfully disable it manually using $ sudo nvme set-feature -f 0x0c -v=0 /dev/nvme0 and the problem goes away. However, after any reboot and even after waking the system from suspend, it is reenabled, causing the system to crash after a short while.
