Does anyone know how to get rid of this:

and some other messages
Sometimes it takes ages before shutdown
I could see that many people have this problem since several years (not only with fedora: debian, ubuntu.... also)
It appears to be often related to hybrid graphics. Is that the case here?
I don't know what exactly is a hybrid graphics... Do you mean that there are two graphic cards? It the case as far I can see:
lspci -vnnn | perl -lne 'print if /^\d+:.+([\S+:\S+])/' | grep VGA returns:
00:02.0 VGA compatible controller [0300]: Intel Corporation 4th Gen Core Processor Integrated Graphics Controller [8086:0416] (rev 06) (prog-if 00 [VGA controller]) 01:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Mars XTX [Radeon HD 8790M] [1002:6606] (rev ff) (prog-if ff)
So, I can see that the integrated graphic card is in use, not the ATI card.
I have two questions: 1- How to activate the ATI graphic card? This card is supported by linux for I bought that computer from Dell with ubuntu installed to be sure that the hardware is linux compatible and the ATI graphic was configured.
2- Why, as the ATI card is not in use, the radeon module is loaded by the kernel?
