After some discussion with rhafer on irc.nue.suse.com:#cloud, I took a look into the openvswitch Ubuntu package and have tested a patch which looks to solve the problem. Submitting a request to our open build service. Log of panic attached in report. Reproducible: Always Steps to Reproduce: 1. systemctl start openvswitch-switch 2. ovs-vsctl add-br foobr0 3. ovs-vsctl del-br foobr0 Actual Results: Kernel panic with kdump enabled, otherwise stack dump along with inoperable networking. Expected Results: Proper deletion of bridge without the above fault. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
