I'm not sure if this is the right mailing list but i saw this patch here
earlier.
On FreeBSD 5.2.1-p9:
First of all i am really annoyed by the lag in mplayer and xmms when
seeking. I found this patch and tried it -- it worked just fine and no
errors or anything.
At the time i was using kde, in wich i will never return(i dont like it
anymore). So i installed gnome and it crashed my system.. page fault
(output in attached file).
After i while i couldn't figure out what was wrong so i did a clean
install. Then i figured it was this sound patch, attached, which had
been working perfecltly before, that crashed my system when i was
loading gnome. I only got the "Loading gnome" splashscreen and the mouse
wouldn't answer becouse i got a page fault. So i deinstalled
gnome-settings-daemon and tried again. Now the gnome_audio applet or
whatever it's name was did the same thing.
So i'm asking if someone could make this patch *gnome compitable* or
give some kind of advice.
