[Bug 34144] Re: sis 760 AGP broken

[sybille]

Hi, sorry for the slow response and thank you very much for attending to
this bug. I wasn't able to reboot to try the Feisty beta CD until this
evening.

Unfortunately, things are still not working for me with Feisty. The xorg.log indicates that agp could not bind and suggests verifying the order in which the agpgart and the radeon modules are loaded.
Lsmod and dmesg both indicate that agp is found, although during boot the size of the agp aperture detected is way off, reading 4M rather than the 128M that is there.

Here's some output from after the boot:

ubuntu at ubuntu:~$ glxinfo | grep render
direct rendering: No
OpenGL renderer string: Mesa GLX Indirect

ubuntu at ubuntu:~$ cat /var/log/Xorg.0.log | grep agp
(II) RADEON(0): [agp] Mode 0x1f004e09 [AGP 0x1039/0x0760; Card 0x1002/0x5960]
(II) RADEON(0): [agp] 8192 kB allocated with handle 0x00000001
(EE) RADEON(0): [agp] Could not bind
(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.

ubuntu at ubuntu:~$ lsmod | grep agp
amd64_agp              13572  0 
sis_agp                 9476  1 
agpgart                33480  3 drm,amd64_agp,sis_agp

ubuntu at ubuntu:~$ cat /var/log/dmesg | grep agp
[  101.260783] Linux agpgart interface v0.101 (c) Dave Jones
[  102.351910] agpgart: Detected SiS 760 chipset
[  102.352228] agpgart: AGP aperture is 4M @ 0xf0000000

Let me know if I can help with debugging. I will be happy to do so,
especially after mid-April since until then I have an on-going project
here that makes rebooting difficult. And thanks again for continuing to
look into this, it's much appreciated. :-)
