There is one image on this forum that seems to work reasonably well with my stream 7, which is Kevin JF's Notion Ink Cain image posted here
https://groups.google.com/forum/#!topic/android-x86/0aj8RZbRCic. It does have kernel 4.0 so that my be why it works, I've tested most of the builds posted here and many from other sites and Kevin JF's is the most usable so far. It doesn't seem to freeze and wifi works. I haven't had a chance to do a lot of testing besides web browsing. It does have an issue with the touchscreen detecting one touch as several touches in quick succession, so if your trying to do any serious typing or setup, use a mouse and keyboard. b.t.w same goes for any type of "swyping" motion, i.e. pulling down the notification drawer or moving to adjacent home screens, the touch issue messes with them but works right if you use a mouse.
