[Michael Reed]

Public bug reported:

[Impact]
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

Version
pciutils-3.3.1-1.1ubuntu1.1

[Testcase]

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


[Regression Potential]

Hi Michael,
This is the only and mandatory patch over the existing pciutils_3.3.1-1.1ubuntu1.1_amd64.deb that is required to fix this:

Sysfs: Read failures of optional attributes are not fatal
https://kernel.googlesource.com/pub/scm/utils/pciutils/pciutils/+/e5bb28afa6124b26cd25506892214a5d3cb9eb60

Verified on the repro-setup, lspci does not crash.

Hope this helps,
Sujith
