Hi :) I wonder if it's an issue with linux-rt 3.10.6-rt3 or randomly something else went wrong. Perhaps caused by 3.10.6-rt3 or not, but a security process or similar seems to be locked on my machine. After installing and booting into the 3.10.6-rt3 an update hanged when checking the keyring. I had to remove /var/lib/pacman/db.lck and could update using 3.10.6-2-ARCH, but when I now try to start a session for 3.10.6-rt3, LightDM hangs when checking the password, I only was able to start one session for this kernel. After downgrading to 3.8.13-rt14-1-rt there isn't this issue anymore and even with 3.10.6-rt3 there were no issues when I want to log in booted in kernel 3.10.6-2-ARCH. In don't know what to check. What log searching for what information. At the moment I simply use 3.8.13-rt14-1-rt. Regards, Ralf
