You have double-checked that the kernel you are trying to boot is
actually the kernel you built using that config file?

Can you post a full dmesg of the failing boot?  You can get this by
using a serial console (see the Handbook).  If you have to copy it by
hand, the critical lines are the sym0 and da0 lines (or any errors
near where those lines should be).  How does it differ from the
dmesg when booting a good kernel?
