Would you mind identifying the pieces of code need to run > for it to work? omap3_has_iva() shows up in just a few places. We did a test by removing the two instances in pm34xx.c. I'm pretty sure that the IVAGRPSEL writes are necessary, since the reset values for those bits are 1, and those definitely need to be cleared. Not sure about the omap3_iva_idle() call; Joe, maybe you can try with just the first hunk of the patch that I sent? - Paul
