Reply To: Diagnostic query: Unexpected kernel panic on macOS Sequoia 15.1 after waking (1794673912)

Migrate the diagnostic focus to the Thunderbolt NHI’s IOThunderboltController::handleLinkEvent() path: capture a kernel debug boot (boot-args="debug=0x144 kextlog=0xfff kdp_match_name=en0") and trigger a controlled sleep/wake cycle while logging via log stream --level debug --predicate 'process == "kernel" && eventMessage contains "Thunderbolt"'. The panic log’s AppleThunderboltNHI::assert() typically maps to kIONHIFatalError during IOThunderboltPort::handleHotPlug()—correlate the timestamp with pmset -g log | grep -e "Wake|Sleep" -A5 to confirm whether the dock’s USB-C billboard device triggers a spurious hot-plug during DarkWake. No user-space app containers (Notes, Mail, Discussions) load kexts capable of triggering this NHI assertion path.
