I have a line that arranges that in /etc/modprobe.d/modprobe.conf. Apparently this is not respected by kmod. I tried the experiment of modprobe -r thinkpad_acpi modprobe thinkpad_acpi (using module-init-tools, that is) and now thinkfan works again. So my next question is, how to ensure that kmod picks up on the option. I guess I ought to be able to find that myself. -- Allin Cottrell Department of Economics Wake Forest University -- To unsubscribe from this list: send the line "unsubscribe linux-hotplug" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
