[rsbac] RSBAC and initrd

Hi all,
I recently compiled a Linux kernel 2.4.24 with RSBAC v1.2.2.
I usually compile kernels with initrd, and in booting the newly
created RSBAC kernel I got and error:

do_umount() [sys_umount()]: umount failed -> calling rsbac_mount for
Device 01:00
umount: /initrd: device is busy

I'm sure it's not a problem with RSBAC privilege because there's no
"NOT_GRANTED by " on the screen, in the log or in /proc/rsbac-info/rmsg

I tested the kernel on a Debian Woody and on a Mandrake 9.2 with the same

I run lsof and infact there are some open files in initrd. 
# lsof | grep initrd
rsbacd  30  root  txt    REG  1,0   70104  17 /initrd/bin/mount
rsbacd  30  root  mem    REG  1,0   90210  27 /initrd/lib/ld-linux.so.2
rsbacd  30  root  mem    REG  1,0 1153784  28 /initrd/lib/libc.so.6
rsbacd  30  root    0u   CHR  5,1          21 /initrd/dev/console
rsbacd  30  root    1u   CHR  5,1          21 /initrd/dev/console
rsbacd  30  root    2u   CHR  5,1          21 /initrd/dev/console

I really don't know how to solve this problem, and I don't like having 
initrd mounted.

Maybe I did something wrong?

Thanks in advance!
