Any after 3.2.x-rt

Maybe I'm doing something wrong, but:

1) All kernels (3.2, 3.8, 3.12, 3.13,...) are working normally without patches;

2) 3.2 works fine in CONFIG_PREEMPT_RT_BASE or CONFIG_PREEMPT_RT_FULL modes;

3) 3.10 not works at all, even without -RT patches;

4) 3.12 work only as CONFIG_PREEMPT_RT_BASE or CONFIG_PREEMPT_RT_FULL in
uniprocessor mode (maxcpus=0, nosmp).  Newer patches (Oct.-Dec.) did not work,
even in RT_BASE mode.

Varia hardware: One Opteron 285, 2-cpus (4 cores). Six Intel Atoms devices
kernels compiled as x86_32.

I have my patches, but I tested both with them and without them.

Behold! 3.12.8-rt11, RT_FULL mode, kernel cmdline: init=/bin/bash

1.
bash: cannot set terminal process group (-1): Inappropriate ioctl for device
bash: no job control in this shell

2.
in single mode: After 2 minutes timeout: see screenshot

3.
command killall -15 freezed system!


Kernel compiled with debug information starts to work normally, but of course
slower. :D
