</span>Then you are either not not running a LITMUS^RT kernel, or you something went wrong during bootup and the /proc/litmus entry was not created (but I’ve never seen that fail before). Check your kernel message log for anything related to LITMUS^RT.<br>
<br>
In particular, if you *are* running a LITMUS^RT kernel and are *not* seeing a /proc/litmus directory, then you should be able to find the error message from the following lines:<br>
<br>
litmus_dir = proc_mkdir("litmus", NULL);<br>
if (!litmus_dir) {<br>
printk(KERN_ERR "Could not allocate LITMUS^RT procfs entry.\n");<br>
return -ENOMEM;<br>
}<br>
<br>

</span>Are you 100% sure this is actually the kernel with the LITMUS^RT patch applied?<br>
