FYI. More info, this bug only occurs when the processors have all triggered on an int1 exception (do_debug) and are all spinning waiting to access the debugger console . It seems to be related to the nmi handler firing off on processors which are waiting to get the shared debugger lock in each debugger.
It does affect processors which may be in both nmi handlers and int1 handlers concurently but is triggered when more than one of the processors has an outstanding int1 exception. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
