After 5 days not using my PC, I decided to get the latest packages which involved an upgraded kernel (4.9.11 -> 4.10.1), renamed and updated radeon graphics drivers (mesa) and some changes to KDE and Xorg. Then things started to get messy after the upgrade. startx would not start the window manager but prompt me with a message saying 'Waiting for X server to begin accepting connections', during a reboot watchdog would halt the process and prompt 'watchdog0: watchdog did not stop' and every once in a while when I am logged in to the CLI a message pops up that says the following:[*randomNumber*] INFO: task kworker/0:1:104 blocked for more than 120 seconds.[*randomNumber*] Not tainted 4.10.1-1-ARCH #1[*randomNumber*] echo 0 > /proc/sys/kernel/hung_task_timeout_secs disables this message(which it does not, I tried)I tried reinstalling everything involving KDE, graphics drivers, xorg, etc. I even tried rolling back all packages on the system to March 1st but running sudo pacman -Syyuu to downgrade everything complains about broken package dependencies. Configuring Arch and KDE to my liking was a pain and I would be very happy not having to reinstall the entire system.
Kernel upgrade (4.10) made XServer and rest of the system fail (Arch)
