Check your partition type and compile it into the kernel, not as a module.
The solution is to include into the kernel your partition type, not as a module, but as a part of the kernel itself. e.g. If you have a resiserfs partition as your boot partition check that the reiser filesystem is checked as an asterisk not as "M" nor empty in your kernel configuration, then save your choices, recompile it, install it and reboot.
That will solve your problem.
