I need that = (or >max_cstate=3D1 to keep my CPU up to speed) Might be an issue fixed in latest kernel. Please try. Thanks, Shaohua |

I don't know if it solves your problem, but i had to activate "Support for hot-pluggable CPUs (Experimental)" (CONFIG_HOTPLUG_CPU=y) in kernel to get suspend to disk working with my Pentium 4 HT. Maybe it helps. Christoph |

Hi Christoph, Shaohua, I do have hotplug_cpu configured into my kernel and disabling/enabling CPUs works just as well in the situation where I did my suspend, s. below. Could it be the setting idle=halt is causing problems? I need that (or max_cstate=1 to keep my CPU up to speed) ... otherwise I get boottimes of an hour) found a patch that didn't help me, so I sticked to the boot param. Haven't gotten round to testing without the param because it would take a matter of hours to boot and suspend :S Probable cause here? Thanks, Karl. |

Hi Christoph, Shaohua, I do have hotplug_cpu enabled and disabling/enabling cpus works in the same situation as the suspend after which the resume does not. Could my setting of idle=halt be a problem? I need it to work around a boot up problem. Thanks, Karl. |
