No luck reproducing this so far. also, just sending the .config that broke would be much better than supplying the seed you used to make it. I'm assuming if we don't use the exact kernel image, with different configs available between versions, the seed will produce different results. Not to mention, I'll spend the time to look at a .config and less likely to spend the time trying to figure out how to create that config. -- Steve
