root failed to mount

[Stefan Johannesdal]

I have been busy and not kept track of head for a while. Now when I 
updated and rebooted I got this:

---8<-----
acd0: FAILURE - INQUIRY ILLEGAL REQUEST asc=0x24 ascq=0x00 sks=0x40 0x00 
0x01
no disk named 'ad0s2b'
Mounting root from hammer:ad0s2d
no disk named 'ad0s2d'
setrootbyname failed
hammer_mountroot: can't find devvp
Root mount failed: 6
---8<-----

Did anything change that would do this unless I do something to prevent 
it? If so, what is that something? If not, any ideas?
