I managed to install the normal most recent kernel (.32-5) by chroot
and it doesn't boot either. In addition I uninstalled mdadm to make sure
it's not the cause of those issues, yet no luck, it fails at
init-bottom because it doesn't manage to mount root.
Could it be that grub2 can't handle a jfs root? I'm pretty much out of
ideas. I'll try downgrading to grub1 tomorrow..
