[gutsy] AGP not available, amd64_agp, drm

[Matti Viljanen]

I have ACER Ferrari 3400 laptop. 3D acceleration works fine on Feisty, but not on Gutsy tribe-1 and tribe-2. It's something about AGP detection/support... Here's something to start with:

kern.log
Jun 30 17:24:45 ubuntu kernel: [ 178.496000] [drm:radeon_cp_init] *ERROR* radeon_cp_init called without lock held
Jun 30 17:24:45 ubuntu kernel: [ 178.496000] [drm:drm_unlock] *ERROR* Process 7776 using kernel context 0

Xorg.0.log
(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. <- How do I check that?

lsmod

Oh, I forgot to mention: I'm using 32-bit Ubuntu on 64-bit machine. (64-bit tribe-2 doesn't even boot, but that's different story)

[Matti Viljanen (direc85)]

Oddly enough, just installing tribe-2 and rebooting fixes this... Investigating!

I'm having the same problem with a mobility radeon 9200 and the rc livecd. A sudo modprobe -r radeon && sudo modprobe radeon fixes it, and after an X restart I get 3d acceleration. For some reason the agpgart module is loaded after the radeon module in the livecd, even though lsmod correctly lists dependencies.

Just installed gutsy from CD, and I also have the same problem with radeon 9200 running on
an intel mobo.

dmesg:

[ 44.692468] [drm:radeon_cp_init] *ERROR* radeon_cp_init called without lock held
[ 44.692512] [drm:drm_unlock] *ERROR* Process 5273 using kernel context 0

Xorg.0.log:

(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.
...
(WW) RADEON(0): Direct rendering disabled

lspci |grep VGA:

01:00.0 VGA compatible controller: ATI Technologies Inc RV280 [Radeon 9200] (rev 01)

lsmod |grep "agp\|radeon":

radeon 125472 0
drm 83348 1 radeon
intel_agp 25620 0
agpgart 35016 2 drm,intel_agp

However in my case reloading the radeon kernel module and restarting X does not help for the broken 3d acceleration.
This seems like a regression from feisty where 3d acceleration worked out of the box on the same machine.

Have you been able to test this in Hardy?

[Seppo Porspakka (sporspak)]

Sorry no, I'm still running feisty.

[Timo Aaltonen (tjaalton)]

You can try the livecd, no need to install.

No problem. I no longer have the system so I can't give any information for this report anymore.
