I'm trying to get this series to work -- i.e. get dream boot up-to serial console.
I tried applying series on 2.6.29, and it failed compilation.
On 2.6.30 and 2.6.32-rc, I get "Uncompressing linux..." feedback on serial, but that's it. Do you still remember what kernel version these should be applied to? .config would be helpful, too... Pavel
