Most watchdogs have a parameter pretimeout, if set to non-zero, it means before the watchdog really reset the system, it will try to panic the kernel first, so kdump could kick in, or, just print a panic stacktrace and then kernel should reset it self. If we are already in kdump kernel, this is not really helpful, only increase kernel hanging chance. And it also make thing become complex as some watchdog triggers the kernel panic in NMI context, which could also hang the kernel in strange ways, and fail the watchdog it self. So just disable this parameter. Also for hpwdt, it have another parameter kdumptimeout, which is just designed for first kernel. The default behaviour is the watchdog will simply stop working if timeouted, trigger a panic, and leave the kernel to kdump. Again, if we are already in kdump this is not helpful. So also disable that. Signed-off-by: Kairui Song <kasong@redhat.com> Acked-by: Lianbo Jiang <lijiang@redhat.com> |
