While icecast could be a trigger case in your setup, there isn't 
anything within icecast that is known to do this, and depending on what 
the actual cause is will also affect how icecast runs afterwards.

I do see a 2.6.15 out so there may already be a fix, but you'll have to 
decode that oops output for the 2.6.14 to see where it fails if you want 
to investigate it.  There is information out there to do the decode but 
we can't say based on what you've said whether it's a driver bug or bad 
hardware.
