When the "hpwdt" module is loaded (even if the /dev/watchdog device is not opened), then kdump does not work. The panic kernel either does not start at all or crash in various places. The problem is that hpwdt_pretimeout is registered with register_die_notifier() with the highest possible priority. Because it returns NOTIFY_STOP, the crash_nmi_callback which is also registered with register_die_notifier() is never executed. This causes the shutdown of other CPUs to fail. Reverting the order is no option: The crash_nmi_callback executes HLT and so never returns normally. Because of that, it must be executed as last notifier, which currently is done. So, that patch returns NOTIFY_OK to keep the crash_nmi_callback executed.
