Hi, hereby my new experiences with my RV515.
# lspci -nnvv | grep "VGA compatible controller" 01:00.0 VGA compatible controller [0300]: ATI Technologies Inc M52 [Mobility Radeon X1300] [1002:714a] (prog-if 00 [VGA controller]) I applied "[PATCH] drm/radeon/kms: add hw_i2c module option" from [1] in addition to pm2-patches (see my last email) and rebuild radeon kernel-module: $ cd $build-dir $ make M=drivers/gpu/drm/radeon clean $ apply_patch $ make M=drivers/gpu/drm/radeon We have now a new module-option "hw_i2c" (0 = disabled, 1 = enabled), This requires to re-generate modules.dep and map files: # depmod Then I rebooted to check new radeon kernel-module. [init-3] # modprobe -r -v radeon # modprobe -v radeon modeset=1 dynpm=1 hw_i2c=1 That is working - no blank screen. But [2] shows also same error when there is a failure (does this error really matter?): ... Mar 18 11:56:40 seduxbox kernel: [ 62.350145] [drm:r500_hw_i2c_xfer], i2c write error 0x00000002 ... Reclocking seems to work (see below) - when I start glxgears and let in run a while you see increasing "e: XXXXX m: YYYYY" - closing glxgears results in downclocking. I will check if starting and closing OpenArena (Anholt benchmark) will result in a blank screen (but this was yesterday).
