I have a post in FreeBSD Stable maling list about my problem. A subject
is: FreeBSD 10.1_RELEASE to FreeBSD 10.2 BETA2

And I wrote:
" Hi!

I upgrade 10.1-RELEASE (amd64) with freebsd-update upgrade to
 FreeBSD 10.2-BETA2 #0 r285646: Fri Jul 17 01:09:28 UTC 2015
root at  amd64

and now I have some problems:

1. VT module doesn't load. 
   In /boot/loader.conf I have:
but it doesn't work. If I manual loada module witk kldload radeonkms I
got just black screen and nothing more.

2. Fireware external disk doesn't work either. In /boot/loader.conf I
have sbp_load="YES" but it doesn't load. If I run kldload sbp it load
and works.
3. The same is with web camera.
   cuse4bsd_load="YES" which I have in /boot/loader.conf doesn't load.
It works if I load with kldload.
In /boot/loader.conf I have also loader_logo="beastie" which doesn't
show picture in menu (it is default one).

In /boot/device.hints I have also some hits which are for my sound card
and it doesn't read them and sound doesn't work correct too.

On FreeBSD 10.1-RELEASE (amd 64) I didn't have problems."


Thank you.
