From: Heiner Kallweit <hkallwe...@gmail.com> [ Upstream commit 4b2d8ca9208be636b30e924b1cbcb267b0740c93 ]
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 CPUs. Add a PCI reboot quirk on affected systems until a more generic fix is available.
