Reply To: Diagnostic query: Unexpected kernel panic on macOS Sequoia 15.1 after waking (1794658911)

[Rachel Kim]

Intermittent wake panics with DisplayPort docks typically stem from a DisplayPort MST (Multi-Stream Transport) hub or DisplayLink manager holding a PreventUserIdleSystemSleep assertion across the sleep transition, causing the IOPlatformPluginFamily watchdog to fire when the NHI attempts to power down the link. Run pmset -g log | grep -e "Wake Requests" -e "Assertions" -e "Kernel.IdleSleepPreventers" --context=5 | tail -100 immediately after a wake event to identify the offending pid/bundleID (look for com.displaylink., com.synaptics., or WindowServer holding DisplayPowerAssertion). If a dock driver is implicated, uninstall its user-space manager, disable “Displays have separate Spaces” (Mission Control) to reduce WindowServer MST topology changes, and test with sudo nvram boot-args="iog=0x0" to disable idle graphics power gating as a mitigation.
