I didn't track these weirdnesses in the scheduler code, but the symptom
is audio skipping and the mouse stops moving when the CPU becomes
busy and the ondemand governor increases the frequency. This lasts for
0.1~0.5 seconds and after that everything is fine.

Thank you all for the quick responses.
