Hi,
A few days ago I reported having trouble getting the kernel to compile with
make -j4. Thank you to all of you who pointed out to me that I had to do a
make depend first.
It works now with make -j2, make -j4, make -j6 but not with make -j8:
# make -j8

Not that it matters much, as I didn't see any improvement between make -j4
and make -j6. I'm just curious. Any ideas?
BTW, here are the results. This is on a Gigabyte 586DX with dual Pentium 166
MMX, 64 MB ram.
