gpart cannot find ada0

[dave jones]

Hi,

I'm running FreeBSD 9-current. Since the bios supports ahci, I enable
it and load ahci module
with no problem. Here's the dmessage:

# dmesg |grep ada0
ada0 at ahcich0 bus 0 scbus0 target 0 lun 0
ada0: <ADATA XPG SSD 64GB J090310> ATA-7 SATA 2.x device
ada0: 150.000MB/s transfers (SATA 1.x, UDMA5, PIO 512bytes)
ada0: 61616MB (126189568 512 byte sectors: 16H 63S/T 16383C)

However, when I run "gpart show ada0", I got:
gpart: No such geom: ada0.

I also load geom_mbr and geom_bsd modules, but it sill can't show ada0.
Does anyone tell me how to solve that issue? Thanks.

Best regards,
Dave.
