Angstrom, udev, and kernel version

Angstrom, udev, and kernel version

[Steffen Sledz]

Since Angstrom updated to udev_151 we've a big problem.

udevd started from within /etc/init.d/udev crashes with

/sbin/udevd -d --debug
1266997931.250494 [297] udev_monitor_new_from_netlink: error getting socket: Invalid argument error initializing netlink socket
1266997931.250718 [297] main: error initializing netlink socket

Searching the internet for this error i found some hints that this udev version requires at least linux 2.6.27. Unfortunately we are forced to use 2.6.24 because of special driver/machine support for hipox. :(

Is there a way to rollback to udev_141 for hipox machine?

Or is there a backport patch available for 2.6.24 to support udev_151?

You can add the following line to either your conf/local.conf or 
conf/distro/include/angstrom-2008-preferred-versions.inc:

PREFERRED_VERSION_udev_hipox = "141"

I too learned that udev-151 (>147) requires glibc-2.9 or higher. Seems like a 
very demanding version of udev...

2.6.27 is only required for signalfd, your error seems to be about a
missing networking option in defconfig.

And I must point out that the move to 151 has been discussed quite well
on the angstrom mailinglist:

Mea culpa.

But, don't panic! No need to revert something. We'll find a solution for us.

Any hints, how we can isolate this problem?

The README in the udev source should have a fairly complete summary of
needed kernel options. If you use angstrom or shr linux.inc will set
them all except CONFIG_NET. So you could try rebuilding your kernel and
see if it works then. If not, compare your .config with the udev readme.
