Bug#483676: drbd8-modules-2.6.25-2-amd64: Can't load drbd module on kernel 2.6.25

[Alessandro Polverini <alex@nibbles.it>]

Package: drbd8-modules-2.6.25-2-amd64
Severity: normal

I get this error while trying to load module drbd: 
FATAL: Error inserting drbd (/lib/modules/2.6.25-2-686/extra/drbd8/drbd/drbd.ko): Unknown symbol in module, or unknown parameter (see dmesg)
In the dmesg log there is nothing about.

I tried also rebuilding the module from the source but the result is the same.

The module package for kernel 2.6.24 works fine.
