Ok, I did exactly that, but CONFIG_TREE_PREEMPT_RCU is
re-enabled. I talked with Pranith Kumar and he suggested I could just
disable preemption (No Forced Preemption (Server)) and that's the only
way to disable CONFIG_TREE_PREEMPT_RCU.
Now I'll try to make the system freeze, then I'll send
you the Call trace.
Thanks.
