>Description:
	PCMCIA cards are power on/off too many times during probe/attach.
	Such a frequent power cycle might damage the devices,
	especially PCMCIA hard disks.

>How-To-Repeat:
	 1. Boot kernel,
	 2. insert a PCMCIA ATA hard disk card,
	 3. the power is on and off three times.

	 1. Insert a PCMCIA ATA hard disk card,
