Title:
kernel stack trace when running openvswitch DEP-8 tests
Status in “linux” package in Ubuntu:
Expired
Bug description:
The DEP-8 test exercises the openvswitch userspace and kernel module
by setting up to bridges, connecting 7 'hosts' to each bridge,
patching the bridges together and then running performance and ping
tests between hosts on different bridges.
The stack trace occurs on teardown of the bridges/switches.
