Hi, I was testing 3.19-rc4 with openvswitch and encountered the splat below.
What version of OVS are you using? Did this work properly with rc3 or an older kernel?
Hi Thomas, Don't know for sure, i haven't seen it before, but on the other hand after a reboot it is running fine now for some time. So it seems it's not reliably reproducible :(. OVS version is current Debian wheezy: ii openvswitch-common 1.4.2+git20120612-9.1~deb7u1 amd64 Open vSwitch common components ii openvswitch-controller 1.4.2+git20120612-9.1~deb7u1 amd64 Open vSwitch controller implementation ii openvswitch-pki 1.4.2+git20120612-9.1~deb7u1 all Open vSwitch public key infrastructure dependency package ii openvswitch-switch 1.4.2+git20120612-9.1~deb7u1 amd64 Open vSwitch switch implementations -- Sander
