This really only makes sense if the linux boxen are sending bpdus, but you
could try setting the etherchannel interfaces to "spanning-tree port type
edge trunk".  Of course, if you do so, you should probably run "brctl show"
on your linux endpoints just to ensure they are not somehow running their
bond interfaces in a bridge and sending bpdus.
