$ For now I just went back to an older kernel that works for me.
How older is your kernel?
My kernel build 2000-09-21 JST. It panic when "make release".
Not that old. 2000-10-05. The machine is a dual 266MHz PII. I have
no problem building releases using "NODOC=YES WORLD_FLAGS=-j4" when
the source is not broken. :-) I'm trying now again after the bktr
fix went in.
