I tried remove CONFIG_RT_GROUP_SCHED=y, it still had cpu stall, so I 
just captured the original config.

Ok, here is capture of the kernel without CONFIG_RT_GROUP_SCHED=y

The directory URL is here,

http://192.11.154.97:3333/project/

3.2.18-2.el6.preempt_rt.x86_64-rt29

is the system config.

I have kernel function capture and dmesg output.

BTW, the system will lock up and cpu stall repeatly after the initial 
one. Even "cat /sys/kernel/debug/tracing/trace > trace-out.txt" takes 
very long time.

Thanks,

Dong
