I'm not sure it's related to vlan; I'm using vlans with bridges here (on wm or ixl interfaces) without issue. It may be related to bge, or tap
That's true - it may be related to something other than vlan.I should add, in that case, that this system, along with others, runs bridges with multiple taps, also bridged to bge*, for various qemu VMs and for tinc.
This came up when I tried to set up a bridge and vlan (on bge) to a tap for tinc that was previously running for months with the tap bridged directly to bge, and that never had issues.
OOB serial can be arranged if anyone wants to take a poke. It seems quickly and easily reproducible.
Thanks, John
