When the powercord is plugged/unplugged the whole machine freezes (forced powerdown + reboot needed). Normally when you plug/unplug the power, the processor switches speed from 1.8 to 1.6 GHz and some other power save settings are applied. The problem turns out to be the Intel Speedstep. When I disable this in my Bios the problem goes away, and I can unplug/plug normally with all power save functions enabled in the Bios and kernel. For your information: * The problem is not there with mdk 9.1, and 9.2RC1 (did not try RC2). * the bug is 100% reproducible (everytime) on my machine with mdk 9.2 default kerne;. * the bug could be reproduced with the secure kernel provided by mdk 9.2. * passing the nolapic option to the kernel did not fix it. * enable ACPI, force no APIC (in bootloader options) did not fix it. * Disabling all power save options in the Bios did not work either (even not after recompile).
