sorry, didn't descript it clear in previous post. I did not make much change on RT PREEMPT path. mostly modification done with DTSI. I got some custom driver. something standard orangepi 5b don't have. turn out the extra-driver causing problem. I just disabling all drivers add by me.

@royk I made some changes by disabling certain drivers in the DTSI (audio, Ethernet, etc.). After testing, the kernel is no longer crashing. Now, I am re-enabling the drivers one by one to see if I can identify which one is causing the issue. Your reply has helped me narrow down the problem. Thank you.

@royk Hi royk, one more question. have you ever experience kernel crash. with 5.10.160 rt-patched. I have seen crash when booting, or running cyclictest. not very offten, but it happened when you testing a lot.

@royk Hello, me again. would you share the .config with me. for build 5.10.160 preempt kernel.

@royk thank your information. I download 5.10.160 branch with PREEMPT_RT feature. when compiling kernel, it throw a error for certs fold Make error. No future information even i set KBUILD_VERBOSE=1. and only few file under kernel/certs/* been compiled into *.o. Have you experience this issue. thanks for your time. I think i figure it out. wrong settings in .config relate to certs
