hi！My machine used to run debian 10.7 with realtime kernel (linux-img-rt-amd64)，everything is ok. A four hours cyclictest test has a result with max latency 8 microseconds. Yesterday I upgraded my machine to debian 10.8, 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.
