How to file a helpful issue

Qubes OS release

R4.2

Brief summary

Due to hardware errata, the PCI Advanced Features capability (where FLR registers live) is not properly linked on Intel I219 network card used in Novacustom v5xx laptops. The reset functionality is otherwise confirmed to work.

Steps to reproduce

  1. Try to install Qubes OS on a Novacustom v5xx laptop

Expected behavior

Successful installation.

Actual behavior

Starting sys-net fails with "unable to reset PCI device 0000:00:1f.6" error: https://openqa.qubes-os.org/tests/105991#step/firstboot/142
Enabling no-strict-reset option for this device workarounds the issue, but it weakens sys-net isolation.

Apply the FLR reset quirk before calling the reset too
200610d 
If device got reset in between some other way, the AF FLR capability
would not be visible. Make sure such action still doesn't break device
reset.
