>Description:
	Wd driver cannot handle bad144 talbe properly?
	In my experience, kernel compalins bad sector table is correupted
	when hadrdisk has more than 1024 cylinders.

wd0: bad sector table corrupted
wd0: bad sector table corrupted
boot device: wd0
root on wd0a dumps on wd0b
wd0: bad sector table corrupted
wd0: bad sector table corrupted
wd0: bad sector table corrupted
wd0: bad sector table corrupted

	Maybe, first two of "corrupted" messages are looking for root
	and dump device.  Rests are four partiton in wd0.

>How-To-Repeat:
	1. IDE hard disk (wd1) which has more than 1024 cylinders.
	2. Add "badsect" flag to the disklabel.
	3. Initialize bad144 table with bad144(8).

		# bad144 wd1 1234

	4. Reboot the system and see the boot message.

>Fix:
	Unknown.
