Hi!
We are experiencing that megaraid_mm wont register on a 2.6.25.2 on our production server.
The module are compiled into the kernel, but /dev/megamon0 is not created, and we dont find any signs in eg. /proc/devices so a manual mknod would seem not to work.

We didnt experience this problem on 2.6.24.2 which were our previous kernel.
