I am able to test 3.8, but not for a long time, because I need the computer to 
be operational and with 3.8 I have two issues:
(1) amd drivers not compatible
(2) the remote bundled with my dvb card doesn't work anymore:

I could live with (1), but not with (2). So I will try to reproduce the
bug on 3.8, but it could take some times. Unless you have an idea on how
to fix my remote on 3.8.
