Re: udev uevents start up loading time
I had the same problem. I searched all over the web and the only solution I found was reinstalling arch.

Re: udev uevents start up loading time
There are some modifications in testing initscripts and udev (you need them both) that may help, additionally I output the actual time the uevents take, which is helpful

Re: udev uevents start up loading time
Also disable CONFIG_UEVENT_HELPER_PATH.
$ grep UEVENT /usr/src/linux/.config
CONFIG_UEVENT_HELPER_PATH=""Offline

Re: udev uevents start up loading time
Also disable CONFIG_UEVENT_HELPER_PATH.
For my own kernel package i take the example from the config of the kernel26mm package:
CONFIG_UEVENT_HELPER_PATH="/sbin/udevcontrol"This works until now without any problems and the boot time seems to be the same but i don't measure it. Does anyone knows a link about for what this uevents been needed?

Do you have an idea when the new initscripts and the new udev will be available for x86_64?
