Reply To: Diagnostic query: Unexpected kernel panic on macOS Sequoia 15.1 after waking (1794697892)

The IOPlatformPluginFamily panic frequently masks a secondary IOBluetoothHostController latency starvation event where bluetoothd holds a PreventUserIdleSystemSleep assertion during photolibraryd CloudKit indexing, blocking the TBT NHI link-training window. Stream live assertions via log stream --predicate 'subsystem == "com.apple.bluetooth" && eventMessage contains "PreventUserIdleSystemSleep"' --level debug during wake; confirm if com.apple.photolibraryd holds the assertion >30s. Disable Photos > Settings > iCloud > Optimize Mac Storage, then purge ~/Library/Containers/com.apple.photolibraryd/Data/Library/Caches/CloudKit to force a clean sync token negotiation, reducing wake-time metadata I/O pressure on the APFS snapshot tree.
