OMAP3530 SBL overflow clearing

I am trying to remove ISP SBL overflow interrupts from being generated.  I am clearing the mask:

isp_reg_and( ISP_IRQ0ENABLE, ~IRQ0ENABLE_OVF_IRQ ) ;

But I am still getting the interrupts which eventually will crash our software.  This is done after a zoom operation where we reset the ISP.

Anybody, please help

    Did this question ever get resolved?  I'm interested in knowing why these overflows occur, and how to properly prevent them.  I'm getting them when running images at a high frame rate through the previewer.  I suspect the previewer is trying to convert each frame and running out of memory.  However, my video stream looks like it is unaffected so I'm a bit confused about that.
