Hey there,

using Arch on Hyper-V (Windows 10) Gnome Desktop and Bootloader Grub. When I am using "pacman -Syu" to update my system the system every time goes into "boot loop" after restart. Have tried this mutliple times (because I am restoring snapshot before update). I sadly don't have the knowledge to figure out what is wrong with the update. see attached list of updates and failures. also boot screen.

Also it's not a classic boot loop it looks like arch is trying to start gnome but fails (deksop is flickering). This happens until like 1 minute until it remains in booting up (doing nothing)

What I did:
1) Launching TTY with CTRL+ALT+F2 works

2) Installed as many updates as possible manually.
Only 9 are left and one or more of them are the cause:

Pakete (9) clang-3.8.0-1 libevdev-1.5.1-1 libinput-1.3.0-2 llvm-libs-3.8.0-1
lvm2-2.02.150-1 mesa-11.2.2-1 mesa-libgl-11.2.2-1
xf86-input-evdev-2.10.2-1 xf86-input-libinput-0.19.0-1

3) did not update the linux kernel. (to execlude that failure). Didn't help

4) only downgrade gnome-shell. Didn't help.

Steps to reproduce:
Install Arch with Gnome in Hyper-V and: pacman -Syu
