On some platforms (for example, QCx6490), XO (Crystal Oscillator) shutdown is prevented by Wireless Processor Subsystem votes on interconnect bandwidth and XO unless the WoWLAN magic-packet trigger is enabled. These votes are released only after running: iw phy0 wowlan enable magic-packet Add an udev rule to automatically enable WoWLAN magic-packet support when a Wi-Fi PHY is registered. This rule is provided via a dedicated wowlan-udev package and is not enabled by default. Integrators should include this package only if their platform requires automatic WoWLAN magic-packet enablement.
