I can utilize only 4 CPUs with Jetpack 4.4 (Include Jetpack 4.4 DP、Jetpack 4.4、Jetpack 4.4.1).
The power mode has set to MAXN (sudo nvpmodel -m 0) and run jetson_clocks.
It still can not use all 6 CPUs with Jetpack 4.4 series, but like Jetpack 4.3、Jetpack 4.2 can use all 6 CPUs.

I can not find any relative information about this with google, please help me to solve this problem, thank you a lot.
