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 http://i59.fastpic.ru/big/2014/0127/bc/0f9e04536181286f820ecaae5a8481bc.jpg 3. command killall -15 freezed system! Kernel compiled with debug information starts to work normally, but of course slower. :D -- Pavel.
