Re: [(Solved) boot problem] mount: /new_root:can't find UUiD

What was updated between when it worked and didn't?

Have you tried regenerating the initramfs?  (Given that you installed -lts, I gather a new initramfs was generated for that, but it's still worth a shot).

From the emergency shell, can you `ls /dev/disk/by-uuid/`?

Yes "mkinitcpio -p linux" and "mkinitcpio -P" done.

In the emergency shell: `ls /dev/disk/by-uuid/`

That's sda1.  None of the nvme partitions are there - so this looks like a failure to detect the nvme device.

What about what was upgraded?  Was there a kernel upgrade.  Did you try downgrading?  Have you checked all hardware / cable connections?

Re: [(Solved) boot problem] mount: /new_root:can't find UUiD

I can't downgrade, because i reinstalled the system

Like they said in this post
https://bbs.archlinux.org/viewtopic.php?id=257375

After upgrade to kernel 5.7.8 and lts-5.4.51 linux is not detecting nvme drive and won't boot with both linux and linux-lts

I think i have to wait for 5.8 kernel

There is a patch here https://git.kernel.org/pub/scm/linux/ke … a6f841417a

You can obtain an old kernel package from the ALA.

Or if 5.8.1 would really include the relevant patch, it is available in testing.  The kernel package is one of very few that you could "cherry pick" from testing without causing problems: so you can just download the pkg.tar.zst from the testing repo of your mirror and install it with `pacman -U`.
