After sucesfully upgrading this machine with experimental kde; libc6, mesa, I 
went down and upgraded htpc and kids pc that are

AMD A4-5000
AMD E2-1800

respectively and all did break preventing to log in any way in kde session.
Becasue one of the crash in one machine reported once  a bug in r600_dri.so
ksplashqml[1148]: segfault at 7ffcac73c000 ip 00007f9bf07d5be5 sp 
00007ffcac739bf8 error 6 in r600_dri.so[7f9bf0394000+a86000]

18.0.0-rc4 is now pushed to experimental, please try with it once it's
built but if the driver still crashes, file a bug upstream.
Only tested on one of the failing machines (AMD A4-5000) : works correctly this time (no crash in sddm or sddm-gretter or ksplashscreen, and I manage to log in and get my session)

Only strange message in dmesg output is: radeon_dp_aux_transfer_native: 74 callbacks suppressed.

Note sure I will try to break again kids PC after the nightmare week-end I got due this bug, even if I know how to fix now :-)

So I hope it means they really fixed it upstream for all amd devices...
