If so,
http://www.kernel.org/pub/linux/kernel/people/akpm/patches/2.5/2.5.63/2.5.63-mm1/broken-out/deadline-dispatching-fix.patch
is designed to fix it. - 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/
