r313898 has a bug for i386 architecture, which was fixed in r313934.
Could you compile kernel from r313898 sources with r313934 applied on
top of it ? I mean, take r313898 and apply the changes from r313934
either manually or with patch, but not take any further changes from
svn after r313898.
If such kernel does not boot, I will provide further instructions.
