Removing the aes driver makes the warning from omap_l3_noc disappear. I also tried tried the omap_l3_noc patches from Nishanth Menon that was just posted but it had the same error when the aes driver was built-in. Would it be possible for someone to add hwmod data for the aes driver to the kernel so that the aes could actually work? regards, Joachim Eastwood > Regards, > Santosh > -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
