We recently removed some LAN cards from two 6500s running SXF and it
wasn't totally without issues.

We removed the cards from the two boxes at the same time, and strangely
they lost their IS-IS adjacency (with each other) because of BFD
timeouts. (The interfaces are configured with "bfd interval 100 min_rx
100 multiplier 3".)

Furthermore, one of them made all iBGP neighbors say:

%TCP-6-BADAUTH: Invalid MD5 digest from <offending box>(22964) to <some
neighbor>(179) (RST)

several times, though no BGP sessions were torn down by this. (?)

This was a POP currently not in production, so I don't know if any
traffic forwarding would be disturbed by this.
