Do you run realTimeConfigQuickScan? It's interesting that the ccrma kernel is not recognized as a realtime kernel by this script. But this kernels config parameters seem to be fine.<br>
<br>
Some more questions:<br>
1. Did you write a udev rule for rtc0 and hpet?<br>
2. Have you tried commenting out the lines for pulse-rt and setting memory limit to unlimited?<br>
3. What about max_user_watches and swappiness in your /etc/sysctl.conf?<br>
4. Did you use the server image for installation? When using the server iso you can switch to a mirror near you as installation source and you will a lot of installation options, i.e. another desktop environment.<br>
<br>
