| |
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.
