| Subject: x86/reboot: Add Zotac ZBOX CI327 nano PCI reboot quirk |
| |
| From: Heiner Kallweit <hkallweit1@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. |
