I'll recompile the newest git-sources and see if it's still triggered with hardirq & softirq disabled ... http://www.kerneloftruth.neucode.org/other/crash_ia32_64/ (<-- omploader is down so I'll host the picture somewhere else) hope there's everything revelant to see / read ... I'll recompile the kernel in question with debug-info probably this evening - if I find some time, you guys also need frame-pointers set ? this also happens with rc7-based kernels, btw > Ingo > Mat -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
