I am using padlock on a Via VB8001 Nano board. It doesn't appear to cause any crashes etc. however it does appear to generate thousands of messages per minute, which makes me think that it's slowing down the system as a whole. >How-To-Repeat: kldload padlock geli init -P -e aes -l 256 -K /root/geli.key -s 4096 /dev/da0 geli attach -pk /root/geli.key /dev/da0 newfs /dev/da0.eli mount /dev/da0.eli /mnt cd /mnt dd if=/dev/zero of=file.000 bs=1m count=100 >Fix: None known >Release-Note: >Audit-Trail: >Unformatted:
