Hhm, kernel developer Diego Calleja García  means, the following issue could be Gentoo specific, so I filed this bug here (original bug report can be found here http://bugzilla.kernel.org/show_bug.cgi?id=6458).

Emerging the current sources and doing a "make menuconfig" and leaving the menu immediately with saying "yes" to save the config gives me these messages at the command line:

Beside that I can reproduceable to select the following config options using "make menuconfig":

n22 /usr/src/linux # make menuconfig

#
# using defaults found in .config

Comment 2 Daniel Drake (RETIRED) gentoo-dev

Please explain in detail how you initially configured your 2.6.16-r6 kernel, e.g. did you do this:

emerge =gentoo-sources-2.6.16-r6
cd /usr/src/linux-2.6.16-gentoo-r6
make menuconfig
  and at this point configure the kernel *from scratch*

or did you do something like:

emerge =gentoo-sources-2.6.16-r6
cd /usr/src/linux-2.6.16-gentoo-r6
cp ../my-old-kernel/.config .
make menuconfig
  and at this point view/change configuration options

Comment 3 Toralf Förster gentoo-dev

2006-05-09 08:00:50 UTC

First I made a "make mrproper && make menuconfig") and run into this issue, after that I decided to move the old sources under /usr/src to *.old, emerged the gentoo-sources again and did immediately a "make menuconfig" _without_ copying any old .config file back into the working dir.

At both ways I observed the same behaviour. I am not sure whether I have observed the config errors for previuos releases of the 2.6.16-gentoo sources too, but now it's reproducible at my system :-(

I use a stable Gentoo system, here are the usual infos:

Comment 4 Daniel Gryniewicz (RETIRED) gentoo-dev

2006-05-09 08:26:57 UTC

Okay, I see this too, but only on an x86 box, not an amd64 box (duh, the warnings are from i386/defconfig).  The warnings do not cause the menuconfig to fail.  This can easily be seen by doing:
make mrproper && make defconfig > /dev/null

Comment 5 Daniel Gryniewicz (RETIRED) gentoo-dev

2006-05-09 08:33:14 UTC

Okay, this same thing happens on stock 2.6.16, so it's not a gentoo problem.

Comment 6 Daniel Drake (RETIRED) gentoo-dev

2006-05-09 08:42:22 UTC

This bug isn't about the warnings, its about the fact that you can produce an uncompilable kernel through menuconfig (see the upstream bug)

Comment 7 Daniel Drake (RETIRED) gentoo-dev

2006-05-09 08:43:49 UTC

Toralf, please detail the path that you take around menuconfig to create this uncompilable setup.

Comment 8 Daniel Gryniewicz (RETIRED) gentoo-dev

2006-05-09 09:14:43 UTC

Sorry, I didn't follow the original link. It's *still* not a gentoo bug, as I was able to reproduce with stock 2.6.16.  I get this:

[12:09:56 nox] linux-2.6.16# grep FM801 .config
CONFIG_SND_FM801=y
CONFIG_SND_FM801_TEA575X=m

  LD      .tmp_vmlinux1
sound/built-in.o: In function `snd_fm801_free':
fm801.c:(.text+0x3b1f7): undefined reference to `snd_tea575x_exit'

fm801.c:(.text+0x3b407): undefined reference to `snd_tea575x_init'
make: *** [.tmp_vmlinux1] Error 1


I'll comment on the upstream bug.

Thanks, we'll let them fix it :)

>This bug isn't about the warnings, its about the fact that you can produce an uncompilable kernel through menuconfig (see the upstream bug)
Correct

>Toralf, please detail the path that you take around menuconfig to create this uncompilable setup.

1. unpack kernel sources
2. (optional) make mrproper
3. make menuconfig
  a) "Device Drivers" -> "Sound" -> "ALSA" -> "Generic Devices" -> MPU401 = y
  b) "Device Drivers" -> "Sound" -> "ALSA" -> "PCI devices" -> "FM801" = y
  c) "Device Drivers" -> "Sound" -> "ALSA" -> "PCI devices" -> "TEA5757 Tuner" = m
