[gentoo-user] Kernel 3.14.14 build failure at DEPMOD stage

[gentoo-user] Kernel 3.14.14 build failure at DEPMOD stage

[Walter Dnes]

  Going from 3.12.13 to 3.14.14 using "make old config" and then the
standard build (64 bit).  At the DEPMOD stage near the very end I get...

  DEPMOD  3.14.14-gentoo
/usr/src/linux-3.14.14-gentoo/scripts/depmod.sh: line 57: 27721
Segmentation fault      "$DEPMOD" "$@" "$KERNELRELEASE" $SYMBOL_PREFIX
make: *** [_modinst_post] Error 139

  I've backed out and eselected 3.12.13 again.  Any ideas what gives?  I
can't find anything relevant on Google.  Google search turns up stuff
like so...

1) cross-compiling and using wrong host; I'm not cross-compiling here

2) out of disk space; nope, I've checked and have plenty of space

3) out of memory; on a Lenovo Thinkpad with 6 gigs of RAM?

And yes, /usr/src/linux-3.14.14-gentoo/scripts/depmod.sh line 57 is...

"$DEPMOD" "$@" "$KERNELRELEASE" $SYMBOL_PREFIX

I *hate* when that happens!  Just a few random ideas that may help the
old bulb light up :)

Can you re-emerge 3.12.13 without any errors?

The kernel build system uses perl (not sure about python), so I always
wonder if perl-cleaner may help fix strange new errors.

I'm guessing you're running gentoo-stable on that machine?  Has gcc
been updated recently?  glibc?  linux-headers? perl? python? kmod?

  It fails now, as does 3.12.21-r1.  Fortunately, I always keep 2
kernels around. The production kernel is call "Production" and new builds
always go as "Experimental".  I use lilo to select the version to boot.
Only after booting and running successfully for a couple of weeks do I
run my "promote" script which copies the Experimental kernel and map and
.config backup files over top of their Production equivalants.  So my
Production kernel is not screwed up.

  I tried both "perl-cleaner --all" and "perl-cleaner --reallyall", but
I still have the problem.  Is there a way to manually run depmod?

  Stable x86_64.  glibc, perl, and python were on the list.  This is a
notebook that hadn't been updated for a month or so.
cd to /var/log/portage and ran command

ll -og | grep Aug\ 13 | sed "s/^.*Aug 13 //"

to get a list of what ran that day...

depmod: QM_MODULES: Function not implemented

  Now what?  Anyhow, I tried "lilo -R Experimental" and rebooted.  It
seems to work OK.  I run a monolithic kernel, so modules won't be a

Well, if you have no modules and CONFIG_MODULES=n you can't expect depmod
to work. However, you wouldn't expect it to segfault, so a bug report is
still in order.

With modules active, I don't get a build-failure.
Been running 3.14.14 since it hit stable in the tree.

AFAICT the only time depmod runs is during the "modules_install" phase.
Do you do "make modules_install" when building a kernel?

BTW, the kernel build scripts do use python as well as perl.  Have you
tried python-updater and checked to see if your various "eselect python"
settings are appropriate?

This won't help with your segfault, but you might find "qlop" useful
for that purpose. (app-portage/portage-utils)

What is your "ll" command?  I have it aliased to run 'ls -laF|less' but
yours is obviously something else.

Or use genlop with the --date option, much simpler

genlop -l --date yesterday

  I'm lazy.  I have 2 scripts sitting in /usr/src which I run from
/usr/src/linux.  After running "make menuconfig" or "make oldconfig" I
run ../makeover which goes like so...

#!/bin/bash
make && \
make modules_install && \
cp arch/x86_64/boot/bzImage /boot/kernel-experimental && \
cp System.map /boot/System.map-experimental && \
cp .config /boot/config-experimental && \
lilo

  Once an experimental kernel has been running OK for a couple of weeks,
I promote it to production with the script ../promote

#!/bin/bash
cp /boot/System.map-experimental /boot/System.map-production
cp /boot/config-experimental /boot/config-production
cp /boot/kernel-experimental /boot/kernel-production
lilo

  My lilo boot menu has 2 boot choices, "Production" and "Experimental".

So it's self-inflicted :)

Try replacing that last line with something like 

(grep -q 'CONFIG_MODULES is not set' .config || make modules_install)

  Ouch.  I just reakized that the "&&" means that the cp commands are
not executed.  So I did the following from the commandline from
directory /usr/src/linux

cp arch/x86_64/boot/bzImage /boot/kernel-test
cp System.map /boot/System.map-test
cp .config /boot/config-test

  Then I...
* added a "Test" entry to lilo.conf
* ran "lilo -R test"
* rebooted

  I am indeed running kernel 3.14.14 this time...

disconnected from the net Tuesday through Friday, so things will have to
wait.

  Out of sheer curiosity, will there be a kernel 3.14.15.29 <G>?

So you do have modules in use?

[thimk][root][~] lsmod
Module                  Size  Used by    Not tainted
lsmod: QM_MODULES: Function not implemented

  I think I may have found the solution.  First of all, the system is
running mdev from busybox, instead of udev.  Secondly, I found
https://forums.gentoo.org/viewtopic-t-955120-start-0.html which suggests

* unmerge modutils

* emerge kmod, with the "tools" USE flag.

  Before I screw anything up, does this sound reasonable?

Yes, that's what I did and all's well.

But *don't* do it until you return from your trip, lest the spirit
of desktop environments put a curse on your applications.
