<para>Finding the right watchdog kernel module for a given system is not
trivial. Automatic probing fails very often. As a result, lots of modules
are already loaded before the right one gets a chance.</para>

lists the most commonly used watchdog drivers. If your hardware is not listed there,
the directories
<filename>/lib/modules/<replaceable>KERNEL_VERSION</replaceable>/kernel/drivers/watchdog</filename>
or
<filename>/lib/modules/<replaceable>KERNEL_VERSION</replaceable>/kernel/drivers/ipmi</filename>
give you a list of choices, too. Alternatively, ask your hardware or
system vendor for details on system specific watchdog configuration.

The following table lists some commonly used watchdog drivers. However, this is
not a complete list of supported drivers. If your hardware is not listed here,
you can also find a list of choices in the directories
<filename>/lib/modules/<replaceable>KERNEL_VERSION</replaceable>/kernel/drivers/watchdog</filename>
and
<filename>/lib/modules/<replaceable>KERNEL_VERSION</replaceable>/kernel/drivers/ipmi</filename>.
Alternatively, ask your hardware or
system vendor for details on system-specific watchdog configuration.
