Marcus ReedAPFS snapshot metadata thrashing during com.apple.timeMachine.localsnapshots post-wake indexing can starve the IOPlatformPluginFamily thermal/power budget watchdog, manifesting as a spurious AppleThunderboltNHI timeout. Disable local snapshots entirely via sudo tmutil disablelocal and purge existing snapshots with tmutil deletelocalsnapshots / to eliminate the fsck_apfs -y / snapshot coalesce I/O storm on wake. Run sudo log show --predicate 'subsystem == "com.apple.filesystems.apfs" AND eventMessage CONTAINS "snapshot"' --last 1h to correlate snapshot merge/delete latency spikes >5s with the panic timestamp. If Disk Utility First Aid reports “invalid sibling link” or “checkpoint” errors on the System volume, boot into macOS Recovery and execute diskutil apfs eraseVolumeGroup diskXsY to rebuild the APFS container superblock cleanly.
