Hi again Uli!

Try to recompile the kernel with these options:

...
# RCU Subsystem
(OK) CONFIG_TREE_PREEMPT_RCU=y
(OK) CONFIG_PREEMPT_RCU=y
...
# Kernel Features
(OK) CONFIG_PREEMPT=y
(OK) CONFIG_PREEMPT_RT_BASE=y
(Not present) CONFIG_HAVE_PREEMPT_LAZY=y
(Not present) CONFIG_PREEMPT_LAZY=y
.....
(Not present) CONFIG_PREEMPT_RT_FULL=y
(OK) CONFIG_PREEMPT_COUNT=y
(ARMv7 only, 3.12+ only)CONFIG_HZ_FIXED=0
(MIPS only) CONFIG_HZ_100=y
(ARMv7 only) CONFIG_SCHED_HRTICK=y

# Timers subsystem
(ARMv7 only) CONFIG_HIGH_RES_TIMERS=y 1

# Debug Lockups and Hangs
(OK) CONFIG_TIMER_STATS=y
(OK) CONFIG_DEBUG_PREEMPT=y

# RCU Debugging
(OK) CONFIG_TREE_PREEMPT_RCU=y
(OK) CONFIG_PREEMPT_RCU=y

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

Hi Artyom,

the green coloured settings are already enabled, the red coloured settings cannot be enabled due to different reasons:
- they depend on a certain architecture or minimal kernel version
- they depend on additional patches being applied first

Cheers
Uli
