hi！My machine used to run debian 10.7 with realtime kernel

debian 10.8,
please read about Debian Point Releases ...

and the version of kernel did not change ( 4.19.0-14-rt-amd64), but a new
cyclictest test see a significantly increased max latency with 40 microseconds.
I don't know why, please help me.
someone else might be able to explain cyclictest testing
