I see similar behaviour. stable/8 before the release worked normal.
Since a few days I have apps segfaulting frequently (firefox, pidgin,
mplayer, ...) and have freezes. I configured Kernel debugging and
added a dumpdev but had no luck in getting a dump so far only freezes.
I let the system run frozen for more then five minutes to see if it's
just dumping in the background (I think one cannot see that while in
X). One time the system froze while loading vboxdrv, another time when
I started mplayer. But it happens on other occasions too.
