Getting that the same userspace runs ok in 2.6.27 and config changes do not show immediate reason, I would blame some internal changes in some kernel subsystem. Why at first it infinitely loops in tty/console loading? I can not run bisect, since reboot requires vnc and I'm far from fast channel. Build of the fresh tree with existing config takes almost one hour, but it should not be a major problem. I can do bisection after the weekend, but can test some changes before machine froze with unsuccessful patch. -- Evgeniy Polyakov -- 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/
