    S-video keeps resetting or no S-video at all --> [drm] not detecting due to 00000004

    Dear all,

    I recently updated my distro LMDE to find KMS was re-enabled, which I had disabled previously to allow for manually configuring direct rendering and tv-out at the same time.

    After the upgrade, inxi says:
    Code:
    jb@LMDE-desktop ~ $ inxi -F
System:    Host LMDE-desktop Kernel 2.6.37-2-686 i686 (32 bit) Distro Linux Mint Debian Edition
CPU:       Single core AMD Athlon XP 2800+ (-UP-) cache 512 KB flags (sse) bmips 4375.37 clocked at 2187.688 MHz 
Graphics:  Card ATI R300 AD [Radeon 9500 Pro] X.Org 1.9.4 Res: [email protected], [email protected] 
           GLX Renderer Gallium 0.4 on ATI R300 GLX Version 2.1 Mesa 7.10 Direct Rendering Yes
    ... and with everything default (KMS on, no xorg.xonf, xrandr S-video load detection 1) S-video keeps resetting e.g. the output frequently drops out very shortly to turn up immidiately after resulting in a 'jump' on the tv screen.

    /var/log/messages is loaded with
    Code:
    [drm] not detecting due to 00000004
    disabling load detection and configuring manually
    Code:
    xrandr --output S-video --set "load detection" 0
xrandr --newmode "800x600m"  38.2  800 832 912 1024  600 603 607 624  -HSync +Vsync
xrandr --addmode S-video 800x600m
xrandr --output S-video --mode 800x600m --right-of VGA-0 --crtc 1
    gives no S-video at all and xrandr says 'S-video disconnected 800x600+1152+0'.

    Disabeling modesetting by creating /etc/modprobe.d/radeon-kms.conf:
    Code:
    options radeon modeset=0
    allows properly working tv-out but no direct rendering at all.

    WORKAROUND:
    Finally, with KMS back on, I forced S-video out 'e'nabled by using in Grub the kernel parameter
    Code:
    video=SVIDEO-1:e
    and switched off load detection after logging in:
    Code:
    xrandr --output S-video --set "load detection" 0
    While KMS still picks up the right settings for tv-out, the output isn't 'jumpy' (being reset?) anymore. However my logs are still bloated with
    Code:
    [drm] not detecting due to 00000004
    Anyone any thoughts on this?
