Is xf86-driver-ati 6.8.0 not a proper release? I'm pretty sure the combination of that, 2.6.25-rc3 and CONFIG_DRM_RADEON causes my machine to become unresponsive. I only tried a git build of the driver after the released version was causing issues. Replacing 2.6.25-rc3 with 2.6.24 (still with CONFIG_DRM_RADEON enabled) results in a machine that boots to GDM successfully. Likewise if I disable CONFIG_DRM_RADEON in 2.6.25-rc3 the machine boots to GDM ok. J. -- jid: noodles@jabber.earth.li 101 things you can't have too much of : 42 - Pepsi.
