Hmm.  Without the multilib patch, I get a conflict between pciutils-devel.i686 and pciutils-devel.x86_64 with file /usr/include/pci/config.h

The pciutils-devel-3.1.7-1 packages of both architectures coexist happily on my system.

did you try to update all packages or just one of them? I've tested to use all pciutils-libs and pciutils-devel(-static) on my computer before update and it was working fine. What is your output of: rpm -qa | grep pciutils

I am trying to update all the packages.

I currently have installed:
pciutils-3.1.7-1.x86_64
pciutils-libs-3.1.7-1.x86_64
pciutils-libs-3.1.7-1.i686
pciutils-devel-3.1.7-1.x86_64
pciutils-devel-3.1.7-1.i686

I issue a yum update, it attempts to upgrade all five packages simultaneously to 3.1.7-2, and reports a conflict thusly:

Error Summary
-------------

thanks, I see it too now. (I wonder why it worked last time.) I'm discussing this with upstream right now, how to fix it properly, because upstream does not like the patches that we removed, so we'll prepare different kind of fix.

Incidentally, here's a diff of the two conflicting files:

For me, a short term fix is presumably to remove pciutils-devel.i686

I don't know that I need the i686 devel package right now, but presumably it is included in the x86_64 repository for a reason?

you need pciutils-devel.i686 on x86_64 machine only if you want to compile some package that BuildRequires pciutils-devel and you want to build it as 32bit not 64bit. AFAIK when you do yum install <package>-devel yum installs both versions (if they are present in the repository) unless you have specified multilib_policy=best in your /etc/yum.conf

I've used different approach to fix multilib conflict. New update will be pciutils-3.1.7-3
