You're correct. What you've posted on the screen is exactly what I wanted,
thanks :)

I don't understand this "unknown-block" thing; I've never seen it before
on a 2.4 kernel. Grepping the source of a 2.6.0-test5-mm4 kernel, which is
what I use, shows that the "unknown-block" message comes from this function:

const char *__bdevname(dev_t dev, char *buffer)
{
	struct gendisk *disk;
	int part;

	disk = get_gendisk(dev, &part);
	if (disk) {
		buffer = disk_name(disk, part, buffer);
		put_disk(disk);
	} else {
		snprintf(buffer, BDEVNAME_SIZE, "unknown-block(%u,%u)",
				MAJOR(dev), MINOR(dev));
	}

	return buffer;
}

Which is completely out of my league.

At this point I'd try 2.6.0-test5-mm4 (available at [www,ftp].kernel.org/pub/linux/
kernel/people/akpm/patches/2.6/2.6.0-test5/2.6.0-test5-mm4/2.6.0-test5-mm4.[bz2,gz])
or appeal to one of the Block Device Overlords, like Jens Axboe, for help.
