Public bug reported:

Description:
On a 4 socket server, when #lspci is run, it fails with output:
lspci: Error reading /sys/bus/pci/devices/0000:9a:00.0/label: Operation not permitted

How Reproducible:
Always

Version
pciutils-3.3.1-1.1ubuntu1.1

Steps:
1. Install Ubuntu-Server-16.04.3
2. Observe #lspci

Additional Info:
* Upstream master branch from pciutils works fine in this setup. (https://kernel.googlesource.com/pub/scm/utils/pciutils/pciutils/)

* v3.4.0 also works fine in this setup.

* v3.3.1 fails.

* Going through code quickly, looks like one of the required patches is :
https://kernel.googlesource.com/pub/scm/utils/pciutils/pciutils/+/ef6c9ec3a45992d9e7ef4716d444252baf2013e1

Not sure what other patches might be required for fixing this.
