# Only one watchdog can succeed. We probe the ISA/PCI/USB based
# watchdog-cards first, then the architecture specific watchdog
# drivers and then the architecture independant "softdog" driver.
# This means that if your ISA/PCI/USB card isn't detected that
# you can fall back to an architecture specific driver and if
# that also fails then you can fall back to the software watchdog
# to give you some cover.
