so to be sure that the previous kernel panics where not caused by my graphics card, I tested two other cards : Saphhire Radeon R9 270X from my Windows PC - worked well and was solid even while running unigene heaven ... after just a few minutes doing nothing (or just browsing the web) it crashed again... and a few hours back I decided to test the original Radeon HD 2600XT that came with my mac... and (of course) I got another KP ...

Should I do a fresh installation of Yosemite, maybe using another installer (not SFOTT) ? or does anybody know another solution to this?
