[SOLVED] Updating to Kernel 4.7-1 broke my system

Hi,

I've performed a normal update with

pacman -Syu

And after the reboot, mounting of some partitions (NTFS and Samba) failed.
The recovery mode shell is shown, but my keyboard doesn't work anymore (I've tried three different keyboard), so I cannot do anything.

So I've booted my system using the USB pendrive with the last Arch Linux ISO, mounted my partition, disabled mounting stuff, rebooted the system.

Now I don't have any mount issues anymore, but anyway the system is hanging on the boot log (even if no errors are reported), and my keyboards still not work (CTRL+CANC, CTRL+ALT+Fx doesn't work, Caps Lock led doesn't light up/down).

How can I solve? Could I revert to previous kernel (booting from the USB pendrive and make an arch-chroot to my system partition)?

Thank you.

If you didn't clean your pacman cache in the meanwhile, you should be able to do

pacman -U /var/cache/pacman/pkg/linux-4.6.4-1-x86_64.pkg.tar.xz

to revert back to the previous kernel (assuming you had that version, other tab completion is your friend). Otherwise, get the package from the Arch archives.
BTW, being hit myself from an issue with 4.7 I found snapper with snap-pac (AUR) to be a great recovery solution...

HTH,
Alexander

I'd suggest also installing the LTS kernel (linux-lts) and keep it updated -- that way you will always have a spare kernel to boot when the mainline kernel breaks.

Thank you for your support.

I've solved as suggested by @akobel.

Just to be precise (just to help someone else that has the same problem), I had also to first remove nVidia package and downgrading to previous version:

pacman -R nvidia
pacman -U /var/cache/pacman/pkg/linux-4.6.4-1-x86_64.pkg.tar.xz
pacman -U /var/cache/pacman/pkg/nvidia-367.35-1-x86_64.pkg.tar.xz 

Thank you.
