Description kjb 2007-08-22 21:41:41 UTC
Hello every, it seems some bug in i810 or drm 
kernel modules (linux version
    When X startup, the drm module prints follow message:

[drm] Initialized i810 1.4.0 20030605 on minor 0
mtrr: base(0xe0000000) is not aligned on a size(0x180000) boundary
[drm] Using v1.4 init.
[drm:drm_release] *ERROR* reclaim_buffers_locked() deadlock. Please rework this
        driver to use reclaim_buffers_idlelocked() instead.
        I will go on reclaiming the buffers anyway.
       My kernel configuration file is:

     My xorg.conf is:
Section "Module"
        Load    "bitmap"
        Load    "dbe"
        Load    "dri"
        Load    "extmod"
        Load    "freetype"
        Load    "glx"

Section "Device"
        Identifier      "Intel Corporation 82810E DC-133 CGC [Chipset Graphics Controller]"
        Driver          "intel"
        BusID           "PCI:0:1:0"
        VideoRam        16384

Section "Monitor"
        Identifier      "LG"
        Option          "DPMS"
        HorizSync       40-70
        VertRefresh     80-90

Section "Screen"
        Identifier      "Default Screen"
        Device          "Intel Corporation 82810E DC-133 CGC [Chipset Graphics Controller]"
        Monitor         "LG"
        DefaultDepth    16
                SubSection "Display"
                Depth           16
                Modes           "1024x768"

Section "DRI"
        Mode    0666

      These configurations work fine on linux-2.6.21.

Not a sitewranglers bug.

Same problem here, even though the bug seems to be quite old. I'm running a Dell Optiplex GX150 which has Intel 82815 graphics. Gives errors and the 2D acceleration feels slow i.e. screen is updated slowly [Slowness might also have something to do with the screen resolution -- my lcd screen is 1600x1200 in native resolution, and xorg doesn't allow me to start up in smaller resolution -- but might be caused by mtrr problems as well?] I'm running fluxbox.

I have the same kernel options as the first writer but built-in, not as modules.

Here's the lspci output:

Closing due to inactivity. Reopen if this is still a problem. (You probably didn't get any feedback, as you filed the bug in the wrong category.)
