When building 2.6.7 on a 4way Linux/ia64, "make -j4 modules" doesn't
spawn 4 jobs. I got
5756 pts/0 S 0:00 make -s -j4 modules
5868 pts/0 S 0:00 make -f scripts/Makefile.build obj=fs
7240 pts/0 S 0:00 make -f scripts/Makefile.build obj=fs/nfs
7269 pts/0 S 0:00 /bin/sh -c set -e; ? gcc -Wp,-MD,fs/nfs/.pagelist.o.

7272 pts/0 R 0:00 as -x -o fs/nfs/pagelist.o -
2.4 kernel module build work fine. Any ideas?

Works for me, GNU Make version 3.79.1 building 2.6.7 on ia64. make -j8
modules gives a pstree of
bash(2475)---make(29483)-+-make(29806)---make(30111)---make(30112)---sh(30113)---gcc(30114)-+-as(30116)

| `-cc1(30155)

`-cc1(30133)
Not the full blown 8 way that I asked for, but that is an artifact of
using recursive make instead of a single top level Makefile with all
the dependencies.

BTW, you don't need to bother with a separate 'make modules' step anymore.
'make -jN' should build everything, including the default boot image for
your architecture.

-j8 (and distcc) WFM since 2.6.0 without problems. All CPUs (4+) are at almost 100% during the build.
