R5F1 and R5F27 are proving to be nightmares on my M10000, with all sorts of boot errors ("found no MultiMedia Video Controller!" and a handful of warnings about not being able to access /proc).

On clean installs of both F1 and F27, it seems that /proc is not being mounted, although it is clearly in fstab. Mounting it manually is possible once the machine is booted, but obviously by that time it's too late. However other entries in fstab ARE being mounted properly.

Anyone know why this might be? The system logs don't seem to show anything, and I couldn't find how to get debug output to show why the fstab entry isn't working.
