Reply To: Diagnostic query: Unexpected kernel panic on macOS Sequoia 15.1 after waking (1794718826)

The AppleThunderboltNHI panic often masks a PD contract renegotiation race where the dock’s 100W PDO collapses during wake, causing the Mac’s ApplePMU to assert kIOPMPowerStateChangeFailed (logged as Error 4013-adjacent in UnifiedLog). Capture the USB-PD negotiation trace via sudo powermetrics --show-process-energy -n 1 -i 1000 | grep -A 10 "Thunderbolt" immediately after wake; look for PDO Reject or Hard Reset events. If the dock negotiates 20V/5A but the Mac requests 15V/3A (common on CalDigit/OWC docks with older NVM), the NHI watchdog fires. Fix: Update dock NVM via vendor Windows tool, or force 15V cap via sudo nvram boot-args="tbpd_max_voltage=15000" (requires SIP off).
