Liam O’ConnorIOPlatformPluginFamily PMIC/SMC Handoff & Hibernate Mode Mismatch: The panic indicates the Platform Plugin (X86PlatformPlugin or AppleARMPlatformPlugin) received an invalid P-state/LPM request from the SMC/PMIC during the wake vector, often triggered by a stale hibernatemode setting conflicting with Sequoia’s updated sleep semantics. Confirm pmset -g custom | grep -E "hibernatemode|standby|autopoweroff"; force sudo pmset -a hibernatemode 3 standby 1 autopoweroff 1 (Intel) or ensure hibernatemode 3 is not forced on Apple Silicon (default is 0x80/standby). Reset the SMC/PMIC state via full shutdown + Left Shift+Control+Option+Power (10s) or Apple Silicon power cycle (30s unplugged) to clear stale thermal/P-state tables.
