HI!

Great job. I use RT kernel with ardour, kdenlive and audacity.
Much better with RT kernel!
The linux distribution is  Slackware 14.2

Problem: Real Time vs VirtualBox.
The VM machines do not run.
has use 5.4.61, and now, 5.4.66

dmesg below
has difference "vboxdrv: version magic '5.4.66-rt38 SMP preempt
mod_unload ' should be '5.4.66-rt38 SMP preempt_rt mod_unload '"
Then, I recompile (vboxdrv setup), after [ 2525... ] in dmesg
