Hi,

(sorry for the double post, I initaly sent it to Angstrom's user list
instead of devel list).

while testing angstrom images on a Cortex A8 (i.MX53 QSB), I found that
systemd-gnome-image stays stucked (at least for one night) on :
Starting udev Coldplug all

The kernel is a 2.6.35 with all the recommended options from
http://dominion.thruhere.net/koen/cms/recommended-kernel-config-options-for-a-modern-angstrom-system

With the same configuration, systemd-image boots fine (with a few
seconds wait at the same log line).

Any idea of what could be wrong here ?

Thanks
Eric


Here is the complete log :
VFS: Mounted root (ext3 filesystem) on device 179:1.
devtmpfs: mounted

You need at least these 2 backports:

https://github.com/Angstrom-distribution/meta-ti/blob/dfbcf63963c95a4818865a9a397dae58c0045121/recipes-kernel/linux/linux-omap4-2.6.35.7/0001-ARM-6329-1-wire-up-sys_accept4-on-ARM.patch
https://github.com/Angstrom-distribution/meta-ti/blob/dfbcf63963c95a4818865a9a397dae58c0045121/recipes-kernel/linux/linux-omap4-2.6.35.7/0002-cgroupfs-create-sys-fs-cgroup-to-mount-cgroupfs-on.patch

And recent systemds might require the active_console backport (from .38), but I haven't checked, I'm on .38 or newer for most machines.

regards,

Koen
