Subject: machine check in kernel for a mpc870 board
Date: Tue, 29 Jun 2010 00:59:56 -0700 [thread overview]
Message-ID: <AANLkTinA2ghLxBU41aFAsLM1oXQ8HMASx1eQMDVvi56n@mail.gmail.com> (raw)
I'm porting a mpc870 board to the powerpc arch. The base is the
adder-875 board. My first try to boot the cuImage.my870 is
experiencing a machine check. And I have no clue where to look. Any
help?
