Architecture: i386
Machine: i386
>Description:
	a crashdump to a disk which doesn't have filesystems in use fails
with: "dump device bad" (on i386; on other architectures the diagnostic
message might look different, but the underlying problem is MI).
This is caused by the check:
	/* Make sure it was initialized. */
	if (wd->drvp->state < READY)
		return ENXIO;
in dev/ata/wd.c:1262
If I put a small filesystem onto that disk and mount it, the dump succeeds.
I also suspect that dumps in early startup don't work, whether the disk
das filesystems in use or not. (didn't check this)
>How-To-Repeat:
	dedicate an IDE disk as dump device. look at code
>Fix:
	add some initialisation code to wddump(), or perhaps wdattach()
