mount_nullfs: Operation not supported by device

After looking at the dmesg output more closely one
discrepancy I found was the second last line:

ad6: 238475MB <WDC WD2500JS-55MHB0 02.01C03> at
ata3-master SATA300

It was definitely SATA150 under FreeBSD 6.0, even after
updates. So maybe a problem in the SATA300 driver?

Unlikely. It looks like you don't have kernel nullfs
support enabled.

I am using the generic kernel. Looking through /etc there
is nothing regarding enabling nullfs. I also looked at
GENERIC kernel conf file without luck. How do I enable
nullfs?

Compile it into your kernel or load the module. Read the handbook for
more help.

Or you could come at it the other way; figure out how you did it when
you were running 6.0. The procedure has not changed.
