In development-sources-2.6.0_beta[78]: The sk98lin giga-ethernet driver builds without warnings but cannot be loaded because it cannot find the symbol ip_compute_csum. The message in /var/log/messages is: sk98lin: Unknown symbol ip_compute_csum This is because the include/asm-x86_64/checksum.h declares the variable as extern, but doesn't EXPORT_SYMBOL it (as alpha does for example). The i386 on the othe hand has the ip_compute_csum as an inline function which is why it doesn't need to be inlined. btw. the same problem occurs also for the module ipt_REJECT. Reproducible: Always Steps to Reproduce: 1. install development-sources-2.6.0_beta8 2. enable sk98lin or ipt_REJECT as a module 3. try to load the module Actual Results: The module didn't load but complained about missing ip_compute_csum symbol. Expected Results: The module was loaded into the kernel.

This driver does compile into the kernel fine though. I'm using right now on test8.
While we don't officially support development-sources, we'll see what we can find out for you.
As you've pretty much outlined the problem, and as this is upstream, please post this over to the LKML.
I sent a mail to x86-64.org and they replied that they already have the fix in their patch set, but Linus hasn't accepted it yet (and won't accept non-x86 fixes for a while). Could it be possible to apply the patches from ftp://ftp.x86-64.org/pub/linux/v2.6/ on top of the development-sources for amd64 or maybe create a new amd64-sources for it?
this is already fixed on the livecd, and is in genpatches-2.6-0.3.tar.bz2 we actually fixed it before there was a patch for it. If you bump the GPV to 0.3 in the development-sources-2.6.0_beta9.ebuild you'll get that patch. Also, a gentoo-dev-sources is about to be released which will bring development-sources back down to vanilla, and include all my patches. To see my current patches, look in http://dev.gentoo.org/~brad_mssw/kernel_patches/2.6.0/genpatches-0.3/ Also, it appears that as of -test9-bk3 that sk98lin patch has been accepted into the kernel. Also, I've been denied adding amd64-sources, and told to just put my patches in gentoo-dev-sources. If gentoo-dev-sources becomes like gentoo-sources is for the 2.4 kernel, I'll have to split it though. -Brad
