And add a big old echo at the top saying "You are using start_dev. This script will be removed in a future release!" > b) Switch to the udev 116 way of module loading For now, yes. We know it works, and we can do some more investigation into this. > c) Remove framebuffer module loading from the load-modules script (it > should never have been there in the first place). Agreed. What are the hotpoints in this script as well? Something like this seems inefficient: i="$(/sbin/modprobe -i --show-depends $1 | sed "s#^insmod /lib.*/\(.*\)\.ko.*#\1#g" | sed 's|-|_|g')" We invoke 3 subprocesses here (modprobe, sed, and sed). Surely the two seds can be combined. k="$(echo $BLACKLIST [EMAIL PROTECTED] | sed 's|-|_|g')" j="$(echo [EMAIL PROTECTED] | sed 's|-|_|g')" Hmm, two more seds. # add disablemodules= from commandline to blacklist k="${k} $(echo ${disablemodules} | sed 's|-|_|g' | sed 's|,| |g')" See a trend here? So we have the following in one run of load-modules.sh (if we look back at the version packaged with 116): cat: 1 invocation eval: invocation count depends on results of cat sed: 6 calls, probably not cheap echo: 5+ calls, but probably a shell builtin grep: 1 call This all means we spawn *at least* 8 processes per module passed to load-modules.sh. I can help clean this up and test if anyone else is willing to help. -Dan
