I am using Debian lenny (kernel 2.6.26, Debian package).

Last night, while building a new kernel, the error

showed up after make.

I did not see any related document within kernel source. Web search gave me several sites, however most of them look like for real developer (like contact Linus.)

Question is:
What is this message?
What am I supposed to do next?

Happy Penguins.

You haven't posted the complete message (one line above or below in this case), because if you did

you'd see it offers you the advice of 'make CONFIG_DEBUG_SECTION_MISMATCH=y'. Better pipe output to a file unless you read fast ;-p

Did it stop and wait for your response? As unspawn says, we can't see enough about what's going on, but I get similar pauses when I forget to run "make oldconfig" after downloading a new kernel source. If my *guess* is right, it's just asking you what you want to choose for that configuration item.

Thanks for your reply.

Yes, as unSpawn points out, I should have piped. Message looked like some sort of conflict among modules at the end of 'make'. (actual one is gone...) It was not waiting for any response.

I did 'make CONFIG_DEBUG_SECTION_MISMATCH=y' and I did not see any message.

I was rebuilding my kernel (uncheck some device drivers) by 'make gconfig', so I don't think I forgot to configure.

Anyway, at this moment, I am trying to build a kernel using same .config file under brand new source tree. I do not see the message again. I will update.

Happy Penguins!

I still have that message.

Kernel: arch/x86/boot/bzImage is ready  (#9)
  Building modules, stage 2.
  MODPOST 846 modules
WARNING: modpost: Found 2 section mismatch(es).
To see full details build your kernel with:


WARNING: drivers/scsi/gdth.o(.text+0x397d): Section mismatch in reference from the function gdth_pci_probe_one() to the function .init.text:gdth_enable_int()
The function gdth_pci_probe_one() references
the function __init gdth_enable_int().
This is often because gdth_pci_probe_one lacks a __init
annotation or the annotation of gdth_enable_int is wrong.

The kernel itself looks like functional. (There are several tiny problems, such as USB memory label does not always show up as a mount point, screensaver does not turn off LCD,.... )

My penguin is Debian lenny kernel 2.6.26 (Debian package).

Happy Penguins!
