After I boot this server with rc6 I don't get any /dev/zdN devices (and thus no zvols). If I export and import the filesystem they show up:
```
[ 101.579449] zd0: p1
[ 101.636243] zd16: p1 p2
[ 101.700731] zd32: p1 p2 p3
[ 101.749898] zd48: p1
[ 101.822565] zd64: p1
[ 101.876364] zd80: p1
[ 101.926939] zd96: p1
[ 101.999085] zd112: p1 p2
[ 102.108115] zd128: p1 p2
```
While the zd devices are missing, I can still 'zfs list':

```
[root@librescu ~]# zfs list

backup 1.35T 1.32T 144K /backup

storage/traffic-boot 2.06G 1.67T 103M -
storage/traffic-root 12.4G 1.67T 1.57G -
```

This is a regression on rc6 - rc5 worked fine in this regard. No errors in the kernel messages.
