 This sucks. So there is no currently working blacklist for the UDEV autoloader?
This damn thing is loading evbug module thats a debugging module for Christs sake that craps my messages log full of noise on boot!  this is torture. Really! Anybody has a clue what could be done about that? |

Darn! I was just looking into the evbug thing again, and got to this thread, searching for "prevent module load". I even looked in /etc/hotplug/blacklist, and found evbug in there. By the way, "rmmod evbug" makes the chatter stop, as you would expect. I hadn't bothered with it too much because when the logs rotate, the chatter should be highly compressible and not take up too much space. Incidentally, I don't remember selecting it on my kernel build... I think someone clicked it on by default.
But it makes looking for anything in /var/log/messages a real pain in the neck.
So I've just added "/sbin/rmmod evbug" to "/etc/conf.d/local.start". An ugly hack, and there may be a little chatter before it's executed, but better than nothing. I know deselecting it in the kernel build is the right way to go, and next time I need to build a kernel, I will.

I found this page to be extremely helpful for understanding how the udev coldplug works:
https://wiki.archlinux.org/index.php/ModaliasPrimer
It might not directly address the problems people are trying to solve here but it sure helped me understand what the heck is going on. One possible work-around would be to write your own udev coldplug that specifically allows for a blacklist. I haven't tested it but something like this might work: | Code: | list_cold_plug_modules() {
for alias in $(find /sys/devices -name modalias | xargs cat); do
modprobe -R $alias
done
}
for module in $(list_cold_plug_modules | sort -u); do
case ",$BLACK_LIST," in
,$module,) ;;
*) modprobe $module;;
esac
done |
Edit: Removed "echo" that disabled the final modprobe command. |
