Samsung NVME randomly goes down during activity

Support
30

then check the one that needs to be checked …

anyway, once that is done

without the complication of chroot - just use your running system
it is still running, is it?

  • open terminal
  • issue command:
    sudo nano /etc/default/grub
    (that will open the file you need to edit in … an editor (nano)
  • find the 5th line down, which should read:
    GRUB_CMDLINE_LINUX_DEFAULT="quiet udev.log_priority=3"

and append to it, inside the quotes:
nvme_core.default_ps_max_latency_us=0 pcie_aspm=off

so that it then looks like this:
GRUB_CMDLINE_LINUX_DEFAULT="quiet udev.log_priority=3 nvme_core.default_ps_max_latency_us=0 pcie_aspm=off"

that is still only one line

  • save the file

  • run:
    sudo update-grub

and then reboot
