dmesg

we removed option "Support for frame buffer device" kernel config.
but this issue still exists

Is this specific to 915GV? how about 965 and other 915 variant?

yes, it's specific to 915GV. this issue doesn't happen on others.

any idea?

this issue has been resolved.
it's caused by the mismatch between the libdrm and drm kernel module.

 Failed to initialize kernel memory manager i965gm

965gm Failed to initialize kernel memory manager

This also happens with i965GM with the latest xserver, drm, mesa and intel-driver builds from their GIT repos. Unfortunately I have to re-open this bug:

(II) intel(0): [drm] framebuffer mapped by ddx driver
(II) intel(0): [drm] added 1 reserved context for kernel
(II) intel(0): X context handle = 0x1
(II) intel(0): [drm] installed DRM signal handler
(EE) intel(0): Failed to initialize kernel memory manager
(==) intel(0): VideoRam: 262144 KB
(**) intel(0): Framebuffer compression disabled
(**) intel(0): Tiling enabled
(II) intel(0): Attempting memory allocation with tiled buffers.

Xorg.log attached.

Output from the dmesg:

[drm] Initialized drm 1.1.0 20060810

I have compilled all of the gits as per instructions from:


http://dri.freedesktop.org/wiki/Building
http://www.x.org/wiki/CompileXserverManually

The xserver has been built with:

./autogen.sh --prefix=/opt/xorg --enable-debug --enable-xorg --disable-dmx \
 --disable-xvfb --disable-xnest --disable-xwin --disable-xprint \
 --enable-xorgcfg --with-mesa-source=/usr/local/src/mesa --enable-aiglx \
 --enable-xdmcp --enable-glx --enable-dri --enable-kbd_mode 

I am also using 2.6.23-gentoo-r5 with x86.

Please let me know if there is anything else I can add as debugging info.

You're not actually loading the new DRM module, as the current minor number is 12 not 11.  Make sure you don't have stale modules laying around, and next time open your own bug for your own issue.
