Bug Description


Problem: during installation, before configuring the network interfaces, netconf puts down all the network links and cpsw gets suspended - later on the PM code kicks and tries to access the suspended hardware generating an oops

Fix: apply the patches present in:

git://git.launchpad.net/~p-pisati/ubuntu/+source/linux x-master_lp1625177

and recompile.

How to reproduce: try to install an ubuntu-core image using the above patched kernel


trying to assemble a new series 16 ubuntu core image for the beaglebone black i am constantly running into an OOPS on first boot. seemingly related to the NIC driver since the NIC does not work after the OOPS.

syslog can be found at http://paste.ubuntu.com/23202737/

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-xenial' to 'verification-done-xenial'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!
