(In reply to comment #9) You need to include the modules in the initrd. You need radeon and and the drm modules (and fbcon if you want console at boot)
AFAICS that would be drm, drm_kms_helper, i915, nouveau, radeon.
And that would be intel-agp, sis-agp, via-agp.
yes. and fbcon for console on the fbdev provided by the drm.
The issue is that there are no deps from the drm to the appropriate agp module. In an installed system the required agp module is loaded automatically during boot. Then afterwards the drm module once the Xserver gets started.
Since that's not possible in initrd Egbert patched mkinitrd in a way that the correct agp/drm module gets loaded in initrd. But that doesn't work for a LiveCD due to obvious reasons.
I'm not following. What's the problem with including them in the initrd?
If you didn't want to include the AGP modules, you could force radeon to use the on-chip gart by passing radeon.agpmode=-1 on the kernel command line.
That would be something for Tobias to try. And Alex, do you happen to know how Fedora/Ubuntu resolve that timing issue with radeon with their LiveCD? BTW, we've never seen that timing issue with nouveau.
x700 mobility cards are pcie so agp is not used at all. Other distros just include the drm and agp modules in the initrd that they can be loaded at boot time as needed. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
