	No hang on my 2.6.11, Aver 771 + TwinHan VisionPlus test rig.
Maybe this deserves a comment in the source?

-	bttv_reset_audio(btv);
+	/* The following reset causes kernel hangs with some DVB cards which 
use
+	 * bt8xx style audio DMA for other purposes (e.g. TwinHan VisionPlus).
+	bttv_reset_audio(btv);
+	 * Resetting the audio on bt8xx cards is not necessary,
+	 * because the audio drivers should do that when they open the card?
+	 */


Now, how do we get this into 2.6.11.7 (or whatever the next one is)?
