Hi, non of the 3.10.x rt patched kernels does work on my machine. $ ls /usr/src/pkg-linux-rt/linux-rt-3* /usr/src/pkg-linux-rt/linux-rt-3.10.10_rt7-1-x86_64.pkg.tar.xz /usr/src/pkg-linux-rt/linux-rt-3.10.14_rt9-1-x86_64.pkg.tar.xz /usr/src/pkg-linux-rt/linux-rt-3.10.15_rt11-1-x86_64.pkg.tar.xz /usr/src/pkg-linux-rt/linux-rt-3.10.6_rt3-1-x86_64.pkg.tar.xz /usr/src/pkg-linux-rt/linux-rt-3.10.9_rt5-01-x86_64.pkg.tar.xz /usr/src/pkg-linux-rt/linux-rt-3.8.11_rt8-1-x86_64.pkg.tar.xz /usr/src/pkg-linux-rt/linux-rt-3.8.13_rt10-1-x86_64.pkg.tar.xz /usr/src/pkg-linux-rt/linux-rt-3.8.13_rt11-1-x86_64.pkg.tar.xz /usr/src/pkg-linux-rt/linux-rt-3.8.13_rt12-1-x86_64.pkg.tar.xz /usr/src/pkg-linux-rt/linux-rt-3.8.13_rt13-1-x86_64.pkg.tar.xz /usr/src/pkg-linux-rt/linux-rt-3.8.13_rt14-1-x86_64.pkg.tar.xz /usr/src/pkg-linux-rt/linux-rt-3.8.13_rt9-1-x86_64.pkg.tar.xz It's not only on my main install, Arch Linux 64-bit architecture, I verified the issue by building a 3.10.x rt patched kernel for Ubuntu 64-bit architecture too. $ ls /mnt/q/boot/vmlinuz* /mnt/q/boot/vmlinuz-3.10.9-rt5 /mnt/q/boot/vmlinuz-3.5.0-18-lowlatency /mnt/q/boot/vmlinuz-3.6.5-rt14 There were no issues without the rt patch for 3.10 kernels and no issues with kernel versions < 3.10.x with and without rt patch. Usually login doesn't work from lightdm, sometimes it does work, but after a short while terminals hang and the prompt gets lost, switching to tty by Ctrl + Alt + F-keys then doesn't work. Last time I could login, I got $ cat .xsession-errors.rt11 find: `/home/rocketmouse/.Xauthority.??????': No such file or directory weather-Message: getting http://api.yr.no/weatherapi/locationforecastlts/1.1/?lat=51.466702;lon=6.850000;msl=38 PolicyKit daemon disconnected from the bus. We are no longer a registered authentication agent. xfce4-appfinder: Fatal IO error 11 (Resource temporarily unavailable) on X server :0.0. Any info needed about my hardware, from journalctl the kernel's config or something else?
