controller will be queried and the events sent to the SEL on that
device. Otherwise, the events go nowhere since there is nowhere to
send them.

+Poweroff
+--------
+
+If the poweroff capability is selected, the IPMI driver will install
+a shutdown function into the standard poweroff function pointer. This
+is in the ipmi_poweroff module. When the system requests a powerdown,
+it will send the proper IPMI commands to do this. This is supported on
+several platforms.
+
+There is a module parameter named "poweroff_control" that may either be zero
+(do a power down) or 2 (do a power cycle, power the system off, then power
+it on in a few seconds). Setting ipmi_poweroff.poweroff_control=x will do
+the same thing on the kernel command line. The parameter is also available
+via the proc filesystem in /proc/ipmi/poweroff_control. Note that if the
+system does not support power cycling, it will always to the power off.
+
+Note that if you have ACPI enabled, the system will prefer using ACPI to
+power off.
