--- Comment #6 from Gael Le Mignot kilobug@freesurf.fr 2010-05-24 10:59:16 PDT --- I managed to get the logs using network (since without the radeon module, I have black screen and I get a system freeze whenever I try to switch to text console).
It seems that when I don't load the radeon module manually from /etc/modules, it gets loaded automatically later in the boot process, and Xorg isn't happy with that.
Maybe a timing issue ?
