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 />
>>My first time hearing about it<br />
Some more questions:<br />
1. Did you write a udev rule for rtc0 and hpet?<br /></div></blockquote>>>No, but will look for documentation on it on the web.<br /><blockquote type="cite"><div>
2. Have you tried commenting out the lines for pulse-rt and setting memory limit to unlimited?<br /></div></blockquote>>>No. Wouldn't this setting equally affect the normal Kernel. (Standard kernel can schedule realtime). Regardless, I will try the settings and report back. (Don't have access to the computer at the moment)<br /><blockquote type="cite"><div>
3. What about max_user_watches and swappiness in your /etc/sysctl.conf?<br /></div></blockquote>>>I kept the default Fedora installation settings. <br /><blockquote type="cite"><div>
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 /></div></blockquote><div>>>I used the official Workstation ISO. But very good idea on using a leaner desktop manager</div><blockquote type="cite"><div>
