The "unrecognized command line option" is brand new. I did not have time to look into the others. From a testing perspective this release was a nightmare: at times there were more than 100 qemu boot test failures in my tests. Ultimately that means that bisectability will be limited. Not that it helps, but yesterday the situation looked much better than today. Guenter
