Your realtime LSM is somehow not working right, as JACK is unable to run
in realtime mode.
Make sure you are really in group 500 (run "groups" and "grep
500 /etc/group"). Check "dmesg | grep -i realtime" to make sure that
the realtime module is being loaded with the correct options. Also try
unloading realtime LSM and forcibly reloading it from the command line:
# rmmod realtime
# modprobe realtime gid=500
