Linux dual-boot still broken, Bluetooth drops, hibernation fails

The August preview update continued the SBAT crusade against Linux dual-boot systems while adding new problems. Bluetooth devices disconnected randomly. File Explorer’s navigation pane stopped refreshing properly. Resuming from hibernation failed. Memory leaks degraded performance over time. SCCM task deadlocks hit enterprise deployments. It was the second August update to break Linux booting, at which point it was clear Microsoft’s “this won’t affect dual-boot” promise was less a commitment and more a suggestion.
