Hi Jesper,
These are the exact problems that I've been running into with trying to
make a generic kernel for slack. I have not had any luck with it as of
yet. I hope we don't have to make box specific kernels for the install.
That would suck.. but seeing how there are issues.. who knows. I have
emailed the aboot people about the problems with the newer compressed
kernels. Question... when you get a Kernel Oops.. is it right when an
IDE device is detected... like a CDROM?
