Subject[PATCH] x86/reboot/quirks: Add Zotac ZBOX CI327 nano PCI reboot quirk
Date
On this system the M.2 PCIe WiFi card isn't detected after reboot,
only after cold boot. reboot=pci fixes this behavior.
In [0] the same issue is described, although on another system and
with another Intel WiFi card. In case it's relevant, both systems
have Celeron CPU's.
The dicussion in [0] involved the PCI maintainer, and proposal was
to go with the PCI reboot quirk on affected systems until a more
generic fix is available.
