all the newer kernels im compiling pause on udev

hi all, I have come across a little problem when I try to boot any kernel newer than about 2.6.11.12. My current one is fine, but when I compile a newer one using the same config file as for my older one (or even a refined, simplified version) it pauses for a very long time when initialising the udev directory (a good minute or two).

I've tried stripping it down quite a bit but still the problem persists.

any ideas?

oh yea that's a thing
you got to upgrade udev

(im glad im not alone in this problem!)

You get the source code to udev from kernel.org. It's located in the pub/linux/utils/kernel/hotplug directory. Here's a direct link:
http://www.kernel.org/pub/linux/utils/kernel/hotplug/

There's a README file in the tarball that discusses prerequisites for the kernel config (which you should meet if you were using udev previously), and describes how to make the project.

I do not know if there are any special precautions you need to take when overwriting an existing udev installation. It might be worth your while to do some Google searching about that.

Also, I'm just providing info based on what foo_bar_foo suggested. I don't know whether this will fix your problem or not; it's just information on how to get a more recent copy of udev.

I'm with lord helmet
make udevdir=/dev
make udevdir=/dev install

but i'm not sure if there are any gotchas waiting on the other end for you or not.
There certainly might be.
newer versions of udev do the hotplug hook differently i think
got a folder /etc/hotplug.d/? and you are a cantidate for troubles
LFS people were having troubles so i stopped upgrading my kernel rather than try it.
There might be something about it in RELEASE-NOTES that can help you understand if you will have issues.

how rude of me it was to not reply again to this thread!

sorry about that guys, I guess it slipped past me. I know it's much too late now but for anyone reading the final solution was to make the new udev, install the new kernel and then i had to get udev to run as a daemon at boot by adding this line to /etc/rc.d/rc.S:

udevd --daemon

rock on!
