I added some printks in hot_add  :

hotadd

md0: md_check_recovery 2: cleared recovery bits on sb f7fc8480
md: 3830
md: 3838
md: 3846

md 3897: ** mddev=f7fc8480 rdev=f7fc8490

why there is 3 rdevs here ?

very beginning of hot_add_disk

it has changed ? we are here :

	if (mddev->persistent) {
		rdev->sb_offset = calc_dev_sboffset(rdev->bdev);
			printk(KERN_INFO "md %d: ** rdev=%p\n", __LINE__, rdev);
	}
	else
		rdev->sb_offset =

I'm going to add some more printks...
