8.3-BETA1 installation problem

[Omer Faruk SEN]

Hi,

I am trying to install FreeBSD 8.3-BETA1 to a system with ssd disk
recognized as ad6. At fixit mode i can dd device but at installer
(sysinstall) when I configured disk and using "w" installer is unable to
format devices stating that

"Unable to find device node for /dev/ad6s1b in dev. The creation of file
systems will be aborted"

any suggestion on what may be the reason for that or is it a bug on
installer
