• Just a guess,

  Recompile Dadhi.

• I’d rather not have to do that step. I “desire” to make the image and copy to the physical disk with dd and have everything set to go. Not take further time and “recompile” things.

  How do I do that?

• If you are using your package manager to install Asterisk & Dahdi, then I would not suggest that you compile.

• If the kernel changes, then DAHDI needs to be recompiled. It sounds like the kernel did not change, but you might want to check.

• You can leave UEFI on, but should be able to disable secure boot in your BIOS.

  If you are unable to disable UEFI secure boot, then you will need to generate a machine owner key pair, and enroll the public parts on the machines where you want to load DAHDI modules you sign with the private part.

• HI All,

  I tried removing the dahdi directory – re-extracting from source and recompile. Did not help. Still getting the error. I am installing from source.

  Thoughts ?

• Pretty sure Shaun Ruffell nailed it. It sounds like you have secure boot enabled (systems designed to run Windows, which is just about everything but a build-it-yourself PC, will enable this by default). This can usually be turned off the the BIOS. The alternative is to get the module properly signed, which involves doing things beyond my personal experience. If secure boot is on, then simply recompiling the module will not help.

  Fedora is set up so that if you run a vanilla install, it can boot with secure boot (all the modules that come from Fedora kernel repos are signed), but if you add your own module, it won’t be signed unless you do it, which means it won’t load if secure boot is enabled.
