Reply To: Diagnostic query: Unexpected kernel panic on macOS Sequoia 15.1 after waking (1794661940)

The DisplayPort MST hub in your dock likely requires a firmware update addressing the DPCD 00100h link training failure that triggers AppleThunderboltNHI::handleLinkEvent panics on wake; check the vendor’s site for a .dfu payload and apply via Apple Configurator 2 in DFU mode (hold power 10s, release, hold 3s) while the dock is the only connected device. Simultaneously, capture a log collect --last 15m --output /tmp/wake_panic.log filtering for AppleThunderboltNHI and IOPCITunnelCompatible to confirm the link retraining timeout (kIOThunderboltLinkTrainingTimeout). If the dock lacks firmware updates, test with a certified TBT4/USB4 cable bypassing the dock’s internal hub to rule out PHY signal integrity degradation.
