this is what I got with 2.6.11rc3:

make[2]: *** [arch/ppc/boot/images/vmlinux.gz] Error 1
make[1]: *** [uImage] Error 2
make[1]: *** Waiting for unfinished jobs....

also, one time that zImage.chrp was only 570K instead of the expected
1.4M, so netboot failed. But I got no build error.
Any idea what dependency is missing?

That is kinda odd.  My thought is that arch/ppc/boot/ just isn't fully
safe for -j'ing.  Sam, any ideas on how to debug this kinda problem?

The problem is that the images/ sub directory is visited before the
prerequisites are finished.
I have no good way to debug this - I can see it based on the Makefile and
the output Olaf included.

Also the problem Olaf describe is just a cp of a half finished file.


So the fix is to let the images/ directory depends on the rest of the
directories.

Something like this may do the trick:

$(obj)/images: $(addprefix $(obj)/,$(subdir-y) $(bootdir-y))
	$(Q)$(MAKE) $(build)=$@

And then delete the assignment of images to subdir-y


Another solution would be to get rid on the images/ drectory and place
outputfiles where they are being built.

Hopefully the first works, since I really do like having all the various
images we create end up in one spot. :)
