Policy and Kernel Panic

[jim tate]

kernel -2.6.4-305, policy-1.9.2-9, rpm-4.3.1-0.1 .
Can't boot box because:
Error message:
Enforcing mode requested but no policy loaded,Halting now.
Kernel panic :Attempted to Kill init!

Have to go into Linux Resue and in /etc/sysconfig/selinux and enter line
SELINUX=permissive and box will boot properly.
Also notice if I uninstall policy and reinstall I get the follwing error 
message:

/etc/security/selinux/file_contexts:  invalid context 
system_u:object_r:amanda_recover_dir_t on line number 1131-1758
Preparing...                ###########################################

[100%]
Can't open '/etc/security/selinux/policy.16':  No such file or directory
error: %post(policy-1.9.2-9) scriptlet failed, exit status 2

But policy is installing but and /etc/security/selinux/policy. is there 
but a big ? in the file,
but not fully developing.????

Thanks
