Hi,
I am trying to upgrade from an (OE classic built) 2008 Angstrom distro
up to a (OE core built) 2012 Angstrom. The builds are each pretty much
console-image recipes with a few extra packages bolted on.
Everything seems to work OK on the 2012 image except for rebooting, which
hangs (I listed the console output below) when mounted via NFS. If I mount
and boot off of an SD-card it is successful, so my guess some network service
seems to be getting turned off before it's time.
The same kernel seems to reboot fine using the 2008 Angstrom filesystem,
but I appreciate that the older distro didn't use control groups (or systemd),
which is where it seems to be stuck.
Any suggestions as to how to troubleshoot / debug?
Thanks.
