Weird build error

[Peter Nguyen]

Hi,

In applying the patch, it still doesn't work, but in this case, the boot up
stops when trying to load "timer" as per the config file i sent in the last
email. More specifically, this is the output i get when "timer" is loaded:

Attached is a text file showing complete output i get, including the "no RM
attachment" part.
