That's most likely the culprit or at least the major culprit. Nothing
has got rt priority.
Are you sure that you are running the lowlatency kernel? If not, than
you need the boot option 'threadirqs'.
What's the output of
uname -rm
Before you boot the lowlatency kernel or a generic kernel with
boot option 'threadirqs', make USB the head and remove the keyboard from
this list, IOW change it to RTIRQ_NAME_LIST="usb snd".
