Boot message error about fstab

Hello everyone

(This is my first time on the forum as a writter but I've been using Arch since about a year now.)

My problem is the following: I've just intalled archlinux in my new laptop (Asus UX32VD). When preventing arch from erasing boot messages, I find a bunch of error messages like the ones below (not completely exact since I cannot copy-paste)

[2.885659]systemd-fstab-generator[111]: failed to create mount unit file /r
xists. Duplicate entry in /etc/fstab?
[3.678503] [drm: intel-dp-i2c-aux-ch] *ERROR* too many retries, giving up
[6.757586] nouveau E [PBUS] MMIO read of 0x00000000 FAULT
[6.757586] nouveau E [DRM] Pointer to TMDS table invalid
... a bunch of errors concerning package laptop-mode-tools

Note that the funny line break after first line is exactly what is displayed.
Now my fstab seems quite standard to me:

#
# /etc/fstab: static file system information
#
# <file system> <dir> <type> <options> <dump> <pass>
# /dev/sdb3
UUID=438e6152-489d-4578-9485-92e7fed5a8df / ext4 defaults,noatime,discard 0 1

# /dev/sda2
UUID=d98522b4-513b-4d00-a564-bd60340c54ac none swap defaults 0 0

The line for /dev/sdb1 is quite ugly but it is my EFI boot sector so I do not know what to change safely.
Have you any idea of what is wrong ?

Some other information :

I've -S, but then -Rs the nouveau package, so I don't know if the lines with "nouveau E" are refering to that. There is a GPU Nvidia card on the laptop but I have currently only installed the Intel chipset drivers.

sdb is a SSD, sda is a HDD. I chose to partition my system this way for speed, but I don't know if it is the right way, or even if it is OK. When I bought my laptop, the EFI boot sector was on the HDD.

Despite the error message, the system seems to work well.

You have two devices mounted at /boot

I'm guessing that either the ext4 one is no longer required, or the vfat one should be mounted at /boot/efi.

Ok thanks WorMzy, changing to /boot/efi solved that error.
I still have the other errors though.

No problem, welcome to Arch by the way. I don't know about the other messages, but at a guess, your laptop is one of those hybrid whatsits with both Intel and nVidia graphics, which would explain why you're getting intel and nouveau drm messages. You might want to read up on the bumblebee page on the Arch wiki, it's not something that I have any experience with.

Thanks
This is indeed a intel/nvidia hybrid.

Just one more question:
I wasn't able to boot this morning because of a kernel update. I was forced to downgrade with the liveUSB + chroot. As I understand it, it was because of the fact that now I have two initramfs-linux.img : one in /boot, one in /boot/efi. Now, when upgrading, only one of them is replaced by the new one. But when booting, the other one is read, so I had a "filesystem vfat not recognized".

So my question is: does it makes any sense to have two separate partitions /boot and /boot/efi? Wouldn't it be simpler to have just one /boot EFI partition in vfat?

That's right, pacman only knows about /boot/vmlinuz-linux, so it's up to you to find some way to sync this to the EFI partition: https://wiki.archlinux.org/index.php/UE … TUB_Kernel

Personally, I use a solution similar to the one you propose. I mount my EFI partition at /mnt/efi, then I bind /mnt/efi/EFI/arch to /boot. That way, when I upgrade my kernel, pacman automatically installs it into the right directory on my EFI partition.
