Hi,
I'm trying to make omap3isp work with our DM3730 based board.
When I try to boot the kernel I get the following message:

[ 2.450012] Kernel panic - not syncing: Attempted to kill init!
exitcode=0x0000000b
This is due to the following function not being executed at startup:
static int __init omap2_iommu_init(void)
{
printk("%s\n", __func__);
return omap_install_iommu_arch(&omap2_iommu_ops);
}
module_init(omap2_iommu_init);
Does anyone know what could be the reason?
Regards.
