Can you figure out which file(s) need to be compiled with -O1 for the 
kernel to work?  You should be able to do a binary search:  compile half 
of the files with -O1 and keep dividing by two until you've isolated the 
files which are responsible.  Then post your results and I'll look at 
the assembly output to see if anything pops out.  Hopefully the problem 
is isolated to one or two specific source files.
