Heh.. except that kernel has its own issues -- hangs in some kind of screen loop in the Radeon code (?) when trying to shutdown. ctrl-alt-sysrq s+u+s+b gets out of that, but it hangs in a similar fashion during the subsequent reboot. A full power-off was required to get the Radeon video to behave so I could reboot the system with 3.4.16 again. I'm not going to pursue that issue for now, though. -- 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/
