 I'm truly sorry, I thought our crash kernel is configured as RT as well. 
so, as I understand, if I build the RT kernel without preempt enabled I can hit this bug?

Don't worry, I should have been better with the details in the log.

So you should _always_ hit the warning/bug if you compile a kernel
without SMP and RT. If you enable one of these then everything should be
fine.
