modprobe: modprobe: Can't locate module block-major-33

[ew0hfx <ew0hfx@vianw.pt>]

Hi list
I'm trying to create a custom kernel. The problem is this:
   modprobe: modprobe: Can't locate module block-major-33
I get 2 lines: modprobe: modprobe: Can't locate module block-major-33
more 2 lines: modprobe: modprobe: Can't locate module block-major-34
and 8 lines: modprobe: modprobe: Can't locate module block-major-8
I'm trying since 2.4.21 to 2.4.22-pre3.
I check my modules.conf, there's only one line about block-major:
   alias block-major-117 dm-mod

Wath's the problem?
