Greetings,

After receiving a lot of information regarding my query on how to switch from installed to dev kernel (thank you to all the people that shared their knowledge on this subject), I am now facing "invalid signature" error when I reboot with my installed dev kernel. I shared the logs for the build, install and also .config and x509.genkey in the following link.
Please let me know what additional information can help to solve this issue.

I am following the instructions in https://kernelnewbies.org/FirstKernelPatch
and I am at the step where I am supposed to verify that a printout was added to the log after I reboot my dev kernel.

Thanks,
Gidi
