Hi I've raised https://bugzilla.kernel.org/show_bug.cgi?id=84131 and attempted to bisect The bug I'm stumbling on happens on both and Intel Sandybridge and AMD Kabini system - it manifests itself as a hard lockup when the system is under high load If I switch off DynTicks the problem doesn't happen - I bisected by compiling Chromium marking each one good or bad if the system starts to lockup I'm not sure if I've filed the bug under the right Product / Component Please let me know if you'd like any more diagnostics Cheers Mike -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
