I've just in the last couple of days starting playing with the ppc and
ppbus controllers in the 3.1-STABLE kernel. While they do seem to be able
to sense the parallel port in my machine something else, very strange, has
occured. When I attempt to reboot my machine either with ctrl-alt-del or
the reboot command all goes well until the actuall reboot of the machine
occurs, at which point the entire machine locks up. The file system syncs
all seem to happen correctly and the machine is properly halted but will
not reboot and nothing short of a complete removal of power will shut the
machine off and allow me to restart. I'm doing this on a Dell Lattitude
CPi so pulling the power means unplugging it and removing the battery (the
power switch won't respond).
Has anyone else seen behavior like this in -STABLE? In particular I am
interested in getting a parallel zip drive to work but if the necessary
kernel changes cause reboot to not play nice then I am a bit concerned.
There's something going wrong here but I'm not at all sure what, any
insight would be appreciated.
Here's what I know in the way of machine info:

From the kernel config (yes I do know that I have the zip driver commented
out, that's related to another problem).
