+If your IPMI interface does not support interrupts and is a KCS or
+SMIC interface, the IPMI driver will start a kernel thread for the
+interface to help speed things up. This is a low-priority kernel
+thread that constantly polls the IPMI driver while an IPMI operation
+is in progress. The force_kipmid module parameter will all the user to
+force this thread on or off. If you force it off and don't have

these interfaces suck.
The driver supports a hot add and remove of interfaces. This way,
interfaces can be added or removed after the kernel is up and running.
