Just bought one of these netbooks, in the packaging there is an extra insert that mentions switching the SATA controller working mode to compatibility before installing a new OS from a windows XP disk, so it makes sense that compatibility mode makes a difference.

However, after installing Ubuntu 9.10 onto the netbook and having a problem with it freezing randomly and looking at this forum, I switched to compatibility mode and it is still freezing, although it seems to be freezing less often.

It always unfreezes with a touch of the mouse or keyboard, so it isn't terrible, but slightly annoying especially if you leave it copying data.

So, it hasn't completely gone away, but it is happening less often.
