Acer Aspire One D150 ffs_mountroot: can't find rootvp

[Saifi Khan <saifi.khan@xxxxxxxxxxxxxxx>]

Hi:

Downloaded LATEST-i386-master.img and then wrote it to USB pen
drive using the command 
# dd if=LATEST-i386-master.img of=/dev/da0 bs=1m

The Acer Aspire One D150 Netbook (currently running Gentoo) was
booted from the USB pen drive.

Hardware specs of the netbook device are at
http://twincling.org/node/451 

The DragonFlyBSD installer screen was presented and on selecting
either
 'Verbose logging'
 or
 'disable ACPI'
 or
 'Safe mode'

had the following issue.

Mounting root from ufs:da8s1a
tryroot da8s1a
no disknamed 'da8s1a'
setrootbyname failed
ffs_mountroot: can't find rootvp
Root mount failed: 6

Manual root filesystem specification:
. ...
. ..
mountroot> ?
possibly valid devices for root FS:
 "md0" "sg0" "da0" "da0s1" "da0s2" "da0s3"

. ..


Any suggestions on how i can bring up this device ?


thanks
Saifi.
