I updated archlinux with "pacman -Syu" and then when I've restart, the system can't start. This is the report:

Warning: /lib/modules/4.11.9-1-ARCH/modules.devname not found - ignoring

version 232

Error: device 'UUID=b5a9a977-e9a7-4d3d-96a9-dcf9c3a9010d' not found. Skipping fsck.

Error: can't find UUID=b5a9a977-e9a7-4d3d-96a9-dcf9c3a9010d 

You are now being dropped into a emergency shell.

Can't access tty: job control turned off

In that shell my keyboard doesn't work.

I'm trying with a livecd of archlinux: mounting the partitions and using chroot.
I check the uuid of the root partition in "/etc/fstab". It's my fstab:

# /dev/sda2 UUID=b5a9a977-e9a7-4d3d-96a9-dcf8c3a9010d   /           ext4        rw,relatime,data=ordered    0 1  

# /dev/sda1 UUID=FBA9-977B          /boot       vfat        rw,relatime,fmask=0022,dmask=0022,codepage=437,iocharset=iso8859-1,shortname=mixed,errors=remount-ro 0 2  

# /dev/sda4 UUID=a43b8426-c93a-4f32-99c8-9dd5cf645373   /home       ext4        rw,relatime,data=ordered    0 2

And it's the result of "lsblk -f"

I've updated the system again with "pacman -Syu" and I tried to make "mkinitcpio -p linux", but it haven't solved the problem (in spite of the result of the command it's ok). This is the report:

I tried to change the order of HOOKS in "/etc/mkinitcpio.conf". But it doesn't work. This is the current order:

base udev block autodetect modconf filesystems keyboard fsck

"uname -r" returns:

4.11.7-1-ARCH

"pacman -Q linux" returns:

linux 4.11.9-1

The file of warrning "/lib/modules/4.11.9-1-ARCH/modules.devnam" exists.

I tried to install and use "linux-lts" but the result it's the same.
I use grub and I tried to reconfigure it too.

What can I do?

I just forgot mount boot (thank you, jasonwryan).

The solution to this problem, in my case was:

1. Use a livecd to mount all partitions and use chroot.


2. 
   

   Update:

   
   
   

   pacman -Syu

   
   


3. 
   

   Regenerate initramfs using:

   
   
   

   mkinitcpio -p linux

   
   


4. 
   

   If you use grub:

   
   
   

   grub-mkconfig -o /mnt/boot/grub/grub.cfg

   
   



5. Restart.

Here is what worked for me (antergos, dual booted with windows 10). It's a slight modification of the above answer.

1. Use a live usb to mount root and boot partitions. The commands for these are here. In this case, my boot partition was the the EFI-boot (fat) partition.


2. 
   

   Update:

   
   
   

   pacman -Syu

   
   


3. 
   

   Regenerate initramfs using:

   
   
   

   mkinitcpio -p linux

   
   


4. 
   

   If you use grub:

   
   
   

   grub-mkconfig -o /boot/grub/grub.cfg

   
   



5. Restart.
