Yes - *that* should work (I haven't tested as I don't run the open driver - but I've used it to suppress other annoying messages) Won't apply until reboot though. For immediate effect:- echo "3 4 1 3" > /proc/sys/kernel/printk >> Where can I find documentation on this? /usr/src/linux-source-2.6.32/Documentation/sysctl/kernel.txt (adjust to suit your kernel) Kind regards -- "Oh sorry, I was taking life seriously." — Bill Hicks -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
