Re: Vaio Can't reboot after kernel upgrade

Indeed I did - and that was the problem. Thanks - for others who may have
rushed headlong into upgrading into devfs, what I did to fix it was to
boot to a rescue disk, type "linux root=/dev/hda4" (insert your /
partition there), and edit /etc/fstab to use the devfs style devices
(e.g., /dev/discs/disc0/part4).
