Lately, ever since I installed gnome3 (3.2), a lot of things have gone unstable. Gnome crashes a lot and pulseaudio too, on every start (I see a segfault by the equalizer module).
My graphic card is on board i945 and I have set mesa to classic mode on sw and i915 families. I partially belive that this is because of -O3 in my make.conf, but compiling a few packages using -O2 didn't do much good either. Moreover, I've been using kde with -O3 since 2011 and never had such a problem. Nevertheless, I'm rebuilding everything with -O2 (emerge -e system, emerge -e world) with gcc 4.7 (no lto) just to see if that fixes the trouble. I have memtested and there's absolutely no problem with the RAM. What do you guys suggest?
