And I forgot :
Laptop , detection of RADEON RS780M HD3200
    and RADEON RV710/MD HD4330/4350/4550
Desktop detection  of RADEON RS690 X1200


Desktop has no problem

New Kernel is up with reverted changes, try it.

[id027102]

New kernel loaded  and reboot : no changeSee harddisk busy , but no display , nor reaction witl ctrl+alt+f1 , only hdd busy

Then the problem are not these 2 config settings.

Ok , but it must be a problem with radeon.ko , if I rename it (no radeon anymore), PC can boot , and I have access to console,
With naturaly no xserver .I don't know what to doI stay with siduction 4.15.15 amd64, perhaps debian 4.16.0 amd64 is working.I investigate furter later , it depends on free timeThanks for your help.

Today updated to kernel 4.17.6-towo.1 , and problem disappeared
Can boot and get xserver when rebooting
Thus solved (for now)
