Hi Updating older kernels with media_build does not remove the old file structure. Running /sbin/depmod will mean the new structure will have two modules of the same name causing module conflicts. The entire old structure needs to be removed first. rm -r /lib/modules/$(uname -r)/kernel/drivers/media Regards Malcolm -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
