machine stuck at cpuidle_pause_and_lock

I'm trying to deploy Caladan, however my testbed stuck completely at cpuidle_pause_and_lock, and nothing can be done to rescue.
CPU:Intel(R) Xeon(R) Gold 6240M CPU @ 2.60GHz
kernel: Linux-kernel 5.2
System : Ubuntu18.04

Is there console/dmesg/syslog output that you can see that you can share? How do you know that it is stuck at cpuidle_pause_and_lock?

there is no output at all.
I only know for sure it stuck at cpuidle_pause_and_lock when insmod the ksched.ko because i use "printk" method to navigate the spot.

Got it. It's pretty odd and I haven't seen something like that before. Are any of the CPUs set to be offline? Maybe you can try a newer Linux kernel version?
