greetings,

sorry it took long to answer, it seems that the time between one flickering to
another has got bigger, from one every sec I have now one every few minutes.

this might be related to the fact that I'm running mesa, libdrm and
xf86-video-ati from git an update them every week.

anyway, here are dmesg and xorg log (I was sure I attached it but it seems that
i didn't).

I'll try now with radeon.disp_priority=2 and report back.
