System is running just fine ever since, putting back in the audio support
makes it unstable again. 

Lockups show up in a couple of minutes or after several hours and always when
running a X session.


>How-To-Repeat:

Load audiodrivers, run GENERIC-SMP kernel on a ASUS P2B-DS
start a xsession with either a windowmaker or gnome desktop and
your lockup will show up sooner or later. Not necessarely when playing audio,
and load does not seem to be a factor too. System lockups hard and good.
No break to serial debugger possible. Sometimes the system may unlock to lockup
again after a few minutes

Trying to hog the system with either mplayer or xmms may speed things up

It was also mentioned by other people that running a dnetc client made the
system unstable, but my case seems to be the audio <-> SMP interaction.

The hard lockups where introduced sometime after 4.3-RELEASE, and it worked
with no instability issues before.


>Fix:

I haven't the faintest idea, but a good starting point would be scrutinizing
the changelogs/changes of the SMP and (new)pcm subsystems.
