[Solved] Cannot boot after kernel upgrade

Today I upgraded the kernel from 4.0.1 to 4.0.4, once I rebooted, there was a filesystem corruption.

I used fsck, to fix it and once I rebooted it failed to load udev Device Manager or something.

I started to look in the forums and appears to be a problem with RAID0 setups, and mine is exactly that.

So, I tried to downgrade to 4.0.1 but I'm currently having problems doing so. What I did was:

I booted with a USB, mounted the partition and arch-chroot.

But once I use pacman -Uv /var/cache/pacman/pkg/linux-4.0.1-1-x86_64.pkg.tar.xz to downgrade the kernel
pacman starts by saying: could not open file /var/lib/pacman/local/<some pkgs> ... I canceld the downgrade and
tried to ls the location and I got a weird error, that looked like a FS corruption, I ran again fsck and it started to fix errors on those exact locations.

I tried the downgrade again, and the same errors still show up. I tried to ls the location again and no FS error this time. So I decided to ignore them and continued to downgrade the kernel.

Once I continue, it shows a bunch of times while the Image is being built an error saying awk: error while loading shared libraries: /usr/lib/libgmp.so.10: invalid ELF header

Now If I reboot there is not even a kernel panic, not even the keyboard works xD Need some help

Re: [Solved] Cannot boot after kernel upgrade

@karol thank you, unfortunately for some of us the news was a bit late, the damage was already done.

Ok, so I saw that some people were able to fix their systems by reinstalling every package with pacman -Qnq | pacman -S --force but some still have some resonating problems.
Since I have a dated full partition clone in an external disk, instead, I'm going to backup my configs and pacman.log, and then restore the system and manually reinstall any renaming packages on pacman.log
