Hi, I'm running 3.10.0 (from openSUSE packages) on an "Intel(R) Core(TM) i7-2600 CPU @ 3.40GHz". I got a hard lockup on one of my CPUs twice, once with backtrace (see attached image). Graphics is the builtin Intel, used with X 7.6 and KDE 4.10beta2 (basically current openSUSE 12.3+KDE). I'm not aware that I had done anything special, just "normal" desktop and development usage, but no heavy compile work at the moment the lockups happened. Any ideas? Eike
