We have 2 Toshiba N210s, NB205 and NB325. Both have the same problem with distros as delivered: disk activity during boot will not proceed unless a key is pressed. I use a Control key since it registers a keypress but does not enter any data. It is not consistent, and can also happen when starting a shell in a terminal window.

Distros include Ubuntu and variants, Mandriva, Fedora, and a few others.

I suspect it is interrupt related.

I have Gentoo with a custom kernel on the NB205 and there is no problem. Unfortunately I've made so many changes to .config that it's hard to find which one(s) fixed the problem.

Any clues?
