see inline below
But a few questions:
1) Are you using the recommended version of dpdk with OVS 2.7 – 16.11 ?
2) Are you getting a crash still or is this post crash ?
3) Was the previous crash still happening with 16.11 or only 17.02 ?
Thanks
Darrell

Subject: [ovs-discuss] Error attaching device to DPDK
Hello,
I have installed OVS 2.7 running. When I do:
1. # ovs-vsctl add-port ovs-ip64-br0 dpdk-p0 -- set Interface dpdk-p0 type=dpdk options:dpdk-devargs=0000:82:00.0
2. ovs-vsctl: Error detected while setting up 'dpdk-p0': Error attaching device '0000:82:00.0' to DPDK. See ovs-vswitchd log for details.
Possibly, the port is not bound.
Check using
$DPDK_DIR/tools/dpdk-devbind.py –status
and see the documentation for more detail
and the log file shows:
1. 2017-03-28T02:04:40.004Z|00064|netdev_dpdk|WARN|Error attaching device '0000:82:00.0' to DPDK
2. 2017-03-28T02:04:40.004Z|00065|netdev|WARN|dpdk-p0: could not set configuration (Invalid argument)
What would cause such a situation?
