After booting Arch today I am unable to enter my usual KDE desktop session. The process stops at the last icon of the loading screen (It essentially looks as in this image http://www.liberiangeek.net/wp-content/ … _thumb.png). I noticed a large KDE upgrade during the last time I did a system update, so I tried to install GNOME and attempt to log into this instead. In this case I am greeted by an error screen (Same message as on this image http://www.overclock.net/content/type/6 … 6/flags/LL). I have tried the failsafe options for both KDE and GNOME with the same behavior in each case. The failsafe GNOME session launches a desktop on my secondary monitor, but my primary monitor still shows the error message.
I am unsure if this is related, but I have noticed what appears to be slow IO performance just after boot. Switching to one of the other TTYs gives a small delay before the login prompt appears. This effect disappears after a few minutes. Also, zsh tab completion hangs during this period and never completes. There is no load to speak of when looking at htop.
The multimonitor setup consists of the secondary monitor running on onboard Intel, while the primary is running on an AMD HD 6800 using the free driver (Not catalyst).
Has anyone else experienced something similar to this in the last few days? Any suggestions how I can debug this, or perform a mass downgrade from the pacman log file to try and identify the culprit?

It appears it was a kernel issue with the ck kernel patches. Running standard Arch kernel yields a working desktop.
