SSD are now becoming cheaper. With better speed, people prefer to use SSD as their main storage device. Unfortunately, there is an error message if you are using NVMe storage when your Linux system is booting: failed to set apst feature.
The message doesn't indicate your NVMe is broken. It is just a message that there is a spesific NVMe feature that currently can't be loaded properly in Linux kernel.
If you are annoyed by the message, you could easily disable it by doing these simple steps:
1. Using your favorite text editor, edit this file:
sudo vi /etc/default/grub
Find the line GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
And put this line: nvme_core.default_ps_max_latency_us=0
To be like this:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nvme_core.default_ps_max_latency_us=0"
2. Save the file and update grub:
sudo update-grub
3. Now, you won't see the message again when your Linux is booting.
