Modprobe - inserting kernel modules

[roncento]

I have built kernel modules, e.g. raw1394.ko, ieee1394.ko, ohci1394.ko, raw1394.ko & video1394.ko

But these modules are failing to load to the kernel.

command:
#modprobe raw1394
FATAL: Error inserting raw1394 (/lib/modules/2.6.32-279.5.2.el6.i686/kernel/drivers/ieee1394/raw1394.ko): Required key not available

my "/var/log/messages" generate the following messages:

kernel: ksign: module signed with unknown public key
kernel: - signature keyid: af767ae12b91b90d ver=4
kernel: Module signed with unknown public key
kernel: ksign: module signed with unknown public key
kernel: - signature keyid: af767ae12b91b90d ver=4
kernel: Module signed with unknown public key

1. is this 'modprobe' has been deprecated?

2. from the 'messages' what is "af767ae12b91b90d ver=4" ?

3. what is 'Module signed with unknown public key'?

4. how can I insert a kernel module, e.g. raw1394 ?

Appreciate your feedback

No answers to your explicit questions but I suspect your problem is due to the way the modules were built.

Please show the output returned by the following --

[code]
[b]uname -r
rpm -q kernel | sort
find /lib/modules -type f -name raw1394.ko
modinfo $(find /lib/modules -type f -name raw1394.ko)[/b]
[/code]
Examination of the output may provide a clue to the cause of the problem.
