This bug leads to an unstable system. Having read all your discussions, I know there is a workaround, but it doesn't seem that everybody agrees this. I'd like to know if this problem is solved in later rt patch series. If yes, could someone be more specific which patch solves it? If not, is applying the above mentioned workaround patch the best solution? Regards, Andrea
