Below are the details. Let me know if anything else is missing.
If I want to try to solve the problem myself where do I start?
thanks

Trying to mount root from ufs:/dev/ad0s1a
Description:
I built a custom kernel with pcvt (vt) console driver enabled.
I removed sc driver from the kernel configuration file.
When I try to boot with this new kernel the machine freezes
just after the kernel starts to load.
How-To-Repeat:
The kernel configuration file:

I did not build any modules:
/etc/make.conf
MODULES_OVERRIDE =
I did not touch the default /etc/rc.d/pcvt
I built and installed the kernel as advised in the user manual:
#cd /usr/src/sys/i386/conf
#/usr/sbin/config VT
#cd ../compile/VT
#make cleandepend
#make depend
#make
#make install
I had no warnings or errors in the process.
Fix:
