Failed to mount boot and swap partition.

Hi there, i've been using arch linux for a year on my 4 year old Asus vivobook laptop. I had it installed on my main 512GB nvme ssd and i installed another 512GB nvme ssd for extra space. after installing, mounting and updating fstab. I rebooted it. After that I started having boot errors mainly failed to boot the boot and swap partition from the main ssd where i had arch installed. BUT after rebooting again, it booted perfectly normal. It boots and doesn't boot frequently.

here's lsblk -f output:

Re: Failed to mount boot and swap partition.

You should not use device names in your fstab but the UUIDs instead. Device names aren't stable and in your case they will swap between nvme1 and nvme0.

Make sure to regenerate your mkinitcpio images with

sudo mkinitcpio -P

so the updated fstab gets included.
