The mdb you provided in the bugzilla ticket misses reports, so it
was unable to parse reports. Which could point to a checksumming
problem.

Enabling promisc probably did not fix the parsing for you, but instead
promisc forces to forward packets upstream on your interface independent
of the mdb. I would assume that even with promisc, your output
from "bridge mdb show" looks rather empty. Can you check?

Thanks :).
