Hi again Uli!

Try to recompile the kernel with these options:

...
# RCU Subsystem
CONFIG_TREE_PREEMPT_RCU=y
CONFIG_PREEMPT_RCU=y
...
# Kernel Features
CONFIG_PREEMPT=y
CONFIG_PREEMPT_RT_BASE=y
CONFIG_HAVE_PREEMPT_LAZY=y
CONFIG_PREEMPT_LAZY=y
.....
CONFIG_PREEMPT_RT_FULL=y
CONFIG_PREEMPT_COUNT=y
CONFIG_HZ_FIXED=0
CONFIG_HZ_100=y
CONFIG_SCHED_HRTICK=y

# Timers subsystem
CONFIG_HIGH_RES_TIMERS=y


# Debug Lockups and Hangs
CONFIG_TIMER_STATS=y
CONFIG_DEBUG_PREEMPT=y

# RCU Debugging
CONFIG_TREE_PREEMPT_RCU=y
CONFIG_PREEMPT_RCU=y

If the kernel build a successful, try to make the tests.
