I've installed Mandriva 2008 Free Beta 1 Ophrys.
It's extremally good! No CD/DVD reading errors on manual tray opening, full support for newer programs. So far I didn't found any errors. My friend also installed it and reported that with new alsa driver he can use his laptop's headphone's output,...
Now I'm looking for a low-latency kernel for music- making. I'll give a try to kernel-mm-2.6.23.
Good work!!!
