No idea what I am looking at here, but I spot sysfs.

This is a pci core bug, not a sysfs one.
I see this in 2.6.35-rc2 as well. 2.6.34 is fine.

does reverting this commit resolve the problem? commit 75568f8094eb0333e9c2109b23cbc8b82d318a3c Author: Alex Chiang <achiang@hp.com> Date: Mon Mar 8 10:24:29 2010 -0700 PCI: create function symlinks in /sys/bus/pci/slots/N/
I did a git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6 and git revert 75568f8094eb0333e9c2109b23cbc8b82d318a3c, followed by my usual build routine. The resulting kernel doesn't show that error on boot anymore.

Please test 2.6.35-rc3, the patch you mention should be reverted: Author: Jesse Barnes <jbarnes@virtuousgeek.org> Date: Fri Jun 11 13:08:37 2010 -0700 Revert "PCI: create function symlinks in /sys/bus/pci/slots/N/" This reverts commit 75568f8094eb0333e9c2109b23cbc8b82d318a3c. Since they're just a convenience anyway, remove these symlinks since they're causing duplicate filename errors in the wild.

Sorry, the commit id: commit 3be434f0244ee059432f92de7e891ee514f41738
-rc3 is fine.
Thanks for confirming.
