You're right as usual. I actually happened to see a 1000baseLX port in dispute
a few years ago, so you made me dig through old emails and tickets.
It was a 6500 facing a 3750, and it was because MSTP BPDUs where incorrectly
tagged, probably due to CSCta17209, we fixed upgrading the 3750.
Probably UDLD wouldn't have helped either.
Thanks,
