Liam O’ConnorThe NHI panic frequently originates from the Thunderbolt NHI firmware failing to relinquish the PCIe link ownership to the AppleThunderboltDPAdapter driver when a paired AirPods handoff or HomeKit Bluetooth LE scan triggers a PME (Power Management Event) storm during dark wake. Disable “Allow Handoff between this Mac and your iCloud devices” and toggle Bluetooth off via blueutil -p 0 in a launchd SleepServices script (/Library/LaunchDaemons/com.local.sleepwake.plist) to isolate the radio coexistence interrupt. If stable, update the dock’s PD controller firmware (CalDigit/OWC/CalDigit utilities) as the root cause is typically a stale Thunderbolt NVM firmware violating the Sequoia 15.1 ACPI _DSM contract for D3cold transitions.
