+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

 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.
