| |
If I enable CONFIG_DRM_RADEON under 2.6.25-rc3 then starting up X using the xf86-video-ati driver (6.8.0 or latest git) causes the machine to become unresponsive; while it still pings and will accept incoming connections they never actually complete and it's not possible to login over a serial console (the actual video console doesn't display anything and the monitor reports a loss of sync).
Disabling the kernel DRM option results in X running successfully. Likewise 2.6.24 works fine with DRM enabled, presumably because the support for the RS690 was only added in 2.6.25-rc
The last messages from the kernel before it becomes unresponsive are:
[drm] Setting GART location based on new memory map [drm] Loading R300 Microcode [drm] writeback test succeeded in 1 usecs
The motherboard in question is an ASUS M2A-VM HDMI, with the analog VGA output being used. The machine is running an AMD64 with Debian unstable. I have put the output of lspci, a non drm Xorg.log and a drm Xorg.log at:
http://the.earth.li/~noodles/xorg-ati-drm/lspci http://the.earth.li/~noodles/xorg-ati-drm/Xorg.0.log-nodrm http://the.earth.li/~noodles/xorg-ati-drm/Xorg.0.log-drm
If I can provide any more useful information please let me know.
