This should have a better explanation. Perhaps BUG("PM: BIOS e820 map conflicts with map from previous boot. S4/hibernate is not supported on this platform. Please contact your hardware vendor.\n"); or pr_crit(FW_BUG "BIOS e820 map conflicts with map from previous boot."); BUG("PM: S4/hibernate is broken on this platform. Please contact your hardware vendor for support.\n"); is more appropriate rather than having them filing a kernel.org BZ or contacting an OS company with a bug that cannot be resolved in software. There are some other instances in the kernel where we've told them to do the same, and it is appropriate to do so here. P.
