Symptoms:
	PHKL_23073:
	(SR: 8606187227   CR: JAGad56435)
	Can not mount the Magneto Optical (MO) device with a 4096
	bytes/sector media. An "unrecognized file system" error
	message will be received when attempting to mount such a
	device.

Defect Description:
	PHKL_23073:
	(SR: 8606187227   CR: JAGad56435)
	When mounting a file system, the drive is considered as a
	block device and is accessed via specfs using fixed block
	io size of 2K. This is ok for all the drives with less or
	equal to 2K bytes sectors. But it is not big enough for
	the devices with the sector size greater then 2K.

	Resolution:
	The block io size for specfs has been changed to 4096 bytes.
