Hi Tianyang,

Are you able to boot into the vanilla Linux 3.0 kernel without the Litmus patch applied?  We should probably figure out if the problem is with the Litmus patch or with the config file.  It is most likely the later, but we can try to rule out the Litmus patch as the cause.  The configuration file needs to be tailored to support your system's hardware.
