Hi, I changed the parameter on cmd line and it works perfectly.
BUT the power consummation increased of 140%
from 6 to 8W.
The REAL pb is to wake up the SSD and this good solution need some other changes ….

This works around the issue for me too , on a Raspberry Pi5 running Debian bookworm…… However the system temperature goes up from 20C to 60C , as this is a box designed to run 24×7 so it’s no good as a long term fix. I guess I’ll just need to buy some better hardware.

Hi Berk,

I’ve had the freezing issue a couple of times before testing your fix. I managed to make the change on my GRUB and updated successfully. The device was running okay for about a week and a half before the same symptoms reappeared.

After rebooting, and running cat /sys/module/nvme_core/parameters/default_ps_max_latency_us it still returned 0 as value. Any other areas that I may need to change to avoid further device lockup?

Hi Dee,

Since you’re on Ubuntu, the command to update GRUB would be: “sudo update-grub”. The command supplied in the guide is for different operating systems.

Give that a shot and let me know how you go. 🙂

Hi Berk and thanks for writing this.
I’m up to the GRUB2.MKConfig but I’m having an error.
I’ve installed “sudo apt install grub2”
Now I type “sudo grub2-mkconfig -o /boot/grub2/grub.cfg” it says command not found

Thanks so much. This saved my bacon when I installed this harddrive as my main drive on my laptop and leading me to crashes I had never seen before in my time on linux. Thanks!!!

Hi. Thanks! It worked for me. I had the same problem with 2 TB Kingston KC2000. It was quite unpleasant time till I came across your article. 🙂

Hi. Thanks!!! It worked perfectly.

Just a note for other users I had to use F10 to save the new changes in the Grub menu because Ctrl+X wasn’t working.

Thanks again. Hopefully we get an upstream fix soon.

So when you pick the USB as boot-device, you get presented with a GRUB boot screen which where you can pick to “Install Fedora …” or “Test this media & install …” Highlight the one you want to go into and press “E” on your keyboard (if you’re booting with EFI). If you’re using legacy mode to boot, you might need to press “TAB”. You will then go into edit mode.

Go to the end of the line “vmlinuz …. …. quiet ” and append “nvme_core.default_ps_max_latency_us=0” (no quotes).

Again, if you’re on UEFI, you will press “Ctrl+x” which will boot into Fedora with the new changes. If you’re using legacy mode, pressing enter should suffice.

Hope this helps!

Hi. Do you know how I could update the Fedora Live ISO with this new command so that I can install it to my ThinkPad?
