>Organization:
>Environment:
3.4-stable as of 26 feb 2000
>Description:
repeated use of kldunload and kldload with most
of the syscons screen savers causes panics.
>How-To-Repeat:
assuming you have the daemon saver installed already ...
this triggers it for me, same for fire saver but not
for the green saver, not tested many others as this
is the only machine I've got and don't fancy the bad
luck of file system damages.
for i in /
do
vidcontrol -t 1
sleep 4
kldunload -i `kldstat | grep daemon | awk '{print $1}'`
kldload /modules/daemon_saver.ko
kldstat
done
