I have upgraded about 40 different QA Farm systems (x86: 32-bit, 64-bit, single-core, multi-core 2 to 32, single-socket, dual-socket; ARM: single-core, multi-core), and they all boot and run without any problem. I didn't see any crash of unknown origin so far. Most systems use the original kernel besides some unimportant farm patches. Several systems have a worst-case latency below 20 microseconds (e.g. https://www.osadl.org/?id=1420 and https://www.osadl.org/?id=1805). Even Raspberry Pi and BeagleBone-Black work like a charm and have reasonably low real-time latency (https://www.osadl.org/?id=1663 and https://www.osadl.org/?id=1601), although they still are not 100% mainline. It is well conceivable that this or one of the next 3.12.X-rtY versions will remind us of the legendary 2.6.33 RT kernel. Seems that an important milestone is being reached. Thanks, -Carsten.
