I can confirm precisely these symptoms with 2.6.35-22. I can see the VLAN packets going out, and I can see the responses leaving a remote system (ARP in this case), but they (responses) do not appear on the Maverick box interface according to tcpdump.
Reverting to 2.6.32 (Lucid) solves problem. I don't know if this is related but I observed other problems with the NICs while running this release, such that they appeared to go out of service completely. But I don't have much useful information about this. This bug affects me because I need to use VLAN with bridging to isolate networks of KVM VMs. -- VLAN support broken https://bugs.launchpad.net/bugs/658460 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
