Xorg.0.log

Thanks for the RV280 fix earlier Alex, here's another on this hardware:
https://bugs.edge.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/297750

[Original Report]
DRI stopped working after upgrade to Intrepid from Hardy. Xorg.0.log states that AGP is not available and DRI has been disabled as a result. This was working well in Hardy.

(II) [drm] DRM open master succeeded.
(II) RADEON(0): [drm] Using the DRM lock SAREA also for drawables.
(II) RADEON(0): [drm] framebuffer handle = 0xd0000000
(II) RADEON(0): [drm] added 1 reserved context for kernel
(II) RADEON(0): X context handle = 0x1
(II) RADEON(0): [drm] installed DRM signal handler
(WW) RADEON(0): [agp] AGP not available
(EE) RADEON(0): [agp] AGP failed to initialize. Disabling the DRI.
(II) RADEON(0): [agp] You may want to make sure the agpgart kernel module
is loaded before the radeon kernel module.

going to need dmesg, sounds more like a kernel bug than a radeon specific issue.

you might want to get the Canonical kernel guys to take a look.

Will do, thanks

dmesg

Here is my dmesg output. I've attached the same file at launchpad too.

so EDAC fights with AGP, AGP loses.

Definitely Canonical kernel team's problem and nothing whatsoever to do with -ati.
