[Ger van Dijck]

Hello ,

First excuses for the "test" I abusively did sent .

I have a new machine : Dell Inspiron 3721 , disk 1 TB, VGA compatible  
controller 3rd generation Rev.09 Intelcorp and Radeon HD 8730 M , Mem size  
8 Gb.

First problem :

I cannot adjust the brightnes of the screen.

Second problem :

When booting I get the message

[2.234578] drm:cpt-error-serr-int-handler *ERROR* PHC encoder A FIFO  
underrun.

Third problem :

After login I get the message : GDBus.Error.org.free  
desktop.Policikit1.Error.Failed :
An autification agent already exists for the given subject.

Fourth problem :

When rebooting I get the message : [429.0649464] watchdog watchdog0:  
watchdog did not stop !

Fifth problem :

When halting the system I get the following message and thereafter I have  
to power off manually :

[439.308512] radeon 000:01::00.0:ring3 stalled for more than 1000msec
[440.686009] [drm:r600-ib-test]*ERROR*radeon:fence wait failed (-35)

GFX ring (-35)
[440.6860931 [drm:radeon resume-kms]*ERROR*ibring test failed (-35)



Be so kind to inform me ,

Ger van Dijck.
