Andy Gospodarek and I have been working offline on the locking issues in bonding over the last several weeks. At the moment, we have a generally stable (but ugly with debug fluff and other yuckies) patch that seems to resolve at least the majority of the various issues. I'm thinking to clean it up for general posting early next week, and address additional problems from there (since it's hopefully at least a big step forward). -J --- -Jay Vosburgh, IBM Linux Technology Center, fubar@us.ibm.com
