Hi, all.
Can somebody suggest a reason why the kernel sources packaged with Red
Hat 7 would compile for SMP, but not for single-CPU?
After a successful compile, I made one change, which was to move the SMP
option from "yes" to "no", and the whole thing breaks. I'm at a loss
for how to even start debugging this, so I enclose the complete screen
output from "make install" (it doesn't get very far) after my sig. Any
thoughts or requests for further information gratefully appreciated.
Thanks,
-m
