Can't see why this change should have affected the main ringbuffer, as it only 
changes how the polling of the cam works, namely actually reporting back when 
there is available space to write to the cam ringbuffer. You are using a CAM?

Could it be that some you had high load on your computer at the moment? Can 
you reproduce this today?

Also that change was done early this morning, are sure you had this change in 
your driver at the time?

Anyone else seeing problems with this change in the ttpci driver and vdr?
