I have some quad port Sun 501-4366 HME nics that I want to use for a bonded adsl project I am using f17 and have it mostly all setup and working, but then I noticed there is an error when pinging

[gene@gene ~]$ ping 192.168.10.75 PING 192.168.10.75 (192.168.10.75) 56(84) bytes of data. 64 bytes from 192.168.10.75: icmp_req=1 ttl=64 time=0.337 ms wrong data byte #54 should be 0x36 but was 0xba

I dont profess to understand why, but apparently this bug only applies to 64 bit kernel with >2g ram I find this bug report on kernel.org:

bugzilla.kernel.org

And this guy has published a very small patch patch: networkbroadcast.co.uk

I havent compiled a kernel since 2004 on some redhat boxes, but I found an up to date howto on here for building a custom kernel

So my questions: How easy is this actually?

Will that howto get me there? Or what problems might I hit?

Any tips or pointers.

This is a very small patch. Do I have to build the whole shebang for that? Is it not just a module?

tia for your time to reply

cd ~/rpmbuild
wget "http://kojipkgs.fedoraproject.org/packages/kernel/3.1.2/1.fc16/src/kernel-3.1.2-1.fc16.src.rpm"
rpm -ivh kernel-3.1.2-1.fc16.src.rpm 
cp alps_Documentation.patch alps_drive.patch SOURCES/
cat kernel_spec.patch | patch SPECS/kernel.spec 
rpmbuild -bs SPECS/kernel.spec --define "_sourcedir SOURCES"
mock -r fedora-16-x86_64 --rebuild SRPMS/kernel-3.1.2-1.fc16.src.rpm --target=x86_64 --define="buildid .z590880"
cd /var/lib/mock/fedora-16-x86_64/result/
rpm -ivh kernel-3.1.2-1.z590880.fc16.x86_64.rpm kernel-devel-3.1.2-1.z590880.fc16.x86_64.rpm

you can see a patch example here : kernel_spec.patch

you also need setup mock , see: how_to_use_mock

Fedora 17 is not longer supported. Update to Fedora 19 and try again. For compile a kernel in a old way (i use the old way method) is easy:

1.- Download .tar.xz from kernel.org and uncompress in /usr/src/ with tar Jxvf 2.- Copy a previous config file from /boot to /usr/src/linux-3.10.7/ for example: cp /boot/config-3.8.9 /usr/src/linux-3.10.7/.config 3.- make menuconfig and edit some thins that if you want 4.- make -jX where X is the number of cores of your CPU +1 5.- make modules_install 6.- make install 7.- Reboot.

For apply any patch: patch -p1 < /patch/to/the/patch into the directory of the uncompressed kernel sources.

The wiki link that you found works. Just follow the steps. Questions like "how easy is it?" are subjective and should not be asked. Give it a whirl.
