 cat /proc/filesystems

tells you what filesystems your kernel can handle
Remember that some filesystem support is compiled as modules, and the
module must be loaded before the kernel can handle that filesystem

A simple check - copy your existing (non-smb) kernel into the place where
grub expectes to find the new kernel, and try rebooting to this
"alternative".

If this succeeds then your new compiled kernel is pants, if it fails then
you haven't got grub configured correctly.

You may not have incuded a kernel option that is needed, or you may have
comiled some options that must be there at boot as modules.
You've not really given enough information to help I'm afraid.
