You can use the platform_check pci test to check that expected
devices on the PCI bus are present, and whether the width or speed is not what is
expected, while the system is in production.
Log in to the command line of the system using an account with root access.
Check the integrity of the PCI devices installed in the system.
If the output is PASS, the PCI devices passed the test. If the output
is FAIL, you should consider taking the system out of production to run
the End-User Diagnostic (EUD) tests.
