Is it possible to get the output when booting in verbose mode? If not,

So the problem is that 7.0-RELEASE works fine for you, but after
upgrading your RELENG_7 source (to what is now 7.1-BETA), the machine
hangs after printing the mount root message. Is this correct?
Here's another question: does booting into single-user exhibit the same
problem as multi-user?

Regarding the Realtek issue: I've CC'd PYUN Yong-Hyeon (surname in
caps), who maintains the re(4) driver for FreeBSD. He might have a
patch available for you to try, or help determine how to get this NIC
working on FreeBSD. He'll probably need more than just pciconf -lv
output, but should be able to work with you.
