Many linux-next builds are done daily: see
  http://kisskb.ellerman.id.au/kisskb/branch/9/

and then I do 25 x86_32 randconfigs and 25 x64_64 randconfigs
daily and fix most build errors that I find in them.
(I am also using a quad-core PC with a cron job that finds the
next day's linux-next, downloads it, and does 50 builds.)

You are welcome to do the same or test mainline (with daily
builds) and/or Andrew Morton's mmotm patchset.

However, boot testing is probably even more helpful, such as you
have already tried.  The /dev/sda2 root problem is probably just a
configuration problem.  Would you like to try to diagnose it?
