Missing modules after kernel upgrade

Post #1 of 6 (4635 views)

Hello all,

I finally got around to updating my kernel to 2.6.20-gentoo-r5 today, but have
run into a snag. I did the usual 'make vmlinux && make modules_install' as
per the guide, copied vmlinux to /boot, edited yaboot.conf, ran 'ybin -v' and
rebooted. Everything seemed good until it started failing on load for
everything I built as a module. A little strange...

OK, so I have a look at my modules:

# ls /lib/modules/2.6.20-gentoo-r5/
build modules.alias modules.dep modules.inputmap modules.ofmap
modules.seriomap modules.usbmap
kernel modules.ccwmap modules.ieee1394map modules.isapnpmap modules.pcimap
modules.symbols source

looks good...
# ls /lib/modules/2.6.20-gentoo-r5/kernel
#

Waaahhh? There's nothing there?

I tried to install them again, thinking I messed up:
# make modules_install
if [ -r System.map -a -x /sbin/depmod ]; then /sbin/depmod -ae -F System.map
2.6.20-gentoo-r5; fi

Nothing...

So where did my modules go? I can assure you all that I *configured* them:
# grep "=m" .config | head -n5
CONFIG_NF_CONNTRACK_ENABLED=m
CONFIG_NF_CONNTRACK=m
CONFIG_NF_CONNTRACK_FTP=m
CONFIG_NF_CONNTRACK_IRC=m
CONFIG_NF_CONNTRACK_TFTP=m
# grep "=m" .config | wc -l
72

Does anyone know what I've done wrong here? This is sort of bizarre. I re-read
the kernel's README, but 'make modules_install' is still valid. As I say,
kernel is 2.6.20-gentoo-r5 (gentoo-sources), machine is a Powermac G5, 64-bit
userland, what else do you need to know? Just ask...

Thanks for consideration,
-d

> So where did my modules go?

Well, this is a new height in user stupidity. I was browsing through the
archives and found a message to this list from *me* that says:

> First of all, when building the kernel the guide says to use "make
> vmlinux && make modules_install" so I faithfully followed the instructions.
> This built me a kernel with no modules for some reason. So I built a new one
> in the fashion I am accustomed to: I did "make && make modules_install".
> This time my modules were made, and I copied vmlinux to /boot.

So I have my answer. It raises another question though: Am I the only one who
has modules go AWOL when doing "make vmlinux && make modules_install". If so,
why? If not, should I be filing a bug against the docs?

What's up with that?

PS: I'm blaming my stupidity on the fact it was about a year ago I built my
last kernel on PPC...

Which document are you refering to? The current docs seem to be in
favour of
# make && make modules_install [1]
already, just saw make vmlinux in some really old handbooks. Perhaps
you are still using an outdated version?

HTH & cheers,

I thought I was going crazy (I searched through all the handbooks), but it
has 'make vmlinux' in the PPC64 2007.0 guide [1] Code Listing 9. I'll check
for a relevant doc bug.

Thanks!

Most proably the "modules" target isn't a dependency of vmlinux. "make
vmlinux modules && make modules_install" should do it if you want
(untested). However, "make && make modules_install" makes sure
everything needed is built.

Thanks. Got it sorted. It seems it was just the 2007.0 PPC64 handbook that was
affected. I reported the bug, and it is already fixed:
