Reply To: Diagnostic query: Unexpected kernel panic on macOS Sequoia 15.1 after waking (1794685902)

The IOPlatformPluginFamily assertion during wake often masks a storage I/O timeout caused by APFS snapshot consolidation colliding with the backupd helper process throttling disk arbitration. Verify snapshot density and purgeable space pressure via tmutil listlocalsnapshots / and diskutil apfs listSnaps /; if counts exceed 20 or purgeable space is stalled, manually thin them with tmutil deletelocalsnapshots before running diskutil verifyVolume / from macOS Recovery to rule out filesystem metadata corruption. A clean Time Machine index rebuild (sudo tmutil disablelocal && sudo tmutil enablelocal) frequently resolves the wake stall without hardware intervention.
