Does anyone know the differences in the 2.4 kernel and 2.6 kernel, as far as acpi is concerned. Here's the deal, my laptop, only seems to restart and shutdown properly, with the 2.4 kernel, but with the 2.6, it's a different story. I have to unplug power and plug it back to restart. I have a Toshiba P25-S670. Thanks in advance.
