2.6.17-rc6 Section mismatch warnings

2.6.17-rc6 Section mismatch warnings

[Barry Scott]

When I built 2.6.17-rc6 I see a lot of warnings after the MODPOST message
about Section mismatch. What did I do wrong in building the kernel and 
modules?

I used these commands to build 2.6.17-rc6 on FC4:
$ tar xjf ~/Downloads/linux-2.6.16.tar.bz2
$ mv linux-2.6.16  linux-2.6.17-rc6
$ cd linux-2.6.17-rc6
$ bzcat ~/Downloads/patch-2.6.17-rc6.bz2| patch -p1
$ cp /boot/config-2.6.16-1.2096_FC4 
~/KernelBuild/obj/linux-2.6.17-rc6/.config
$ make O=~/KernelBuild/obj/linux-2.6.17-rc6 silentoldconfig
(took the defaults for all new config items)
$ make O=~/KernelBuild/obj/linux-2.6.17-rc6 >make-1.log 2>&1
$ make O=~/KernelBuild/obj/linux-2.6.17-rc6 modules >make-2.log 2>&1

Here are some of the warnings:

Nothing (well, I would use "make all" instead of the last 2
commands and I would use ketchup or
http://www.xenotime.net/linux/scripts/grab-kernel-rc
to optionally download and create new kernel dirs. :)

I'll look at the warnings.  Some of them are noise/bogus,
I expect...

I edited out the duplicate warnings to cut down the size of the mail.
Let me know if you want the full list.

It would be helpful if someone could look at/work on the
section mismatches in the isdn and sound drivers...

I have 6 new patches to post, then I'll be
sweeping the net drivers soon.

Can you see if
http://www.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.17-rc6/2.6.17-rc6-mm1/broken-out/megaraid_mbox-fix-section-mismatch-warnings.patch
fixes the megaraid warning for you?

The alsa folks have fixed their problem and you should see a patch from them
shortly.

Any news on the net driver problems?

Sorry, I posted patches for a bunch of net drivers and forgot to
copy you on them.  On Sat., 2006-June-10, on the netdev mailing
list, patches for smc, hp, & 3c5zz:
