kernel/alsa oops

[walt <wa1ter@myrealbox.com>]

I update from Linus every day, so I'm running his latest alsa
updates as of 03April.

I just got this kernel oops, which is reproducible:

This is what I did to reproduce this oops:

I was playing a video with mplayer, which I put on 'pause'.
I started listening to BBC Radio with RealPlayer-10.0.7.
I then took mplayer off of pause, which instantly produced
this kernel oops.

Judging from the behavior of all the apps I was running at
the time, it seems that RealPlay was the one which actually
crashed.  Everything else seems okay.

Any ideas?  Need any further info?
