Hi,

I'm having encountering the above errors, it is persistent with every boot. It occured both on buster and on buster-minimal.

Note that specifically the micrel kmod fails verification, but because it shares a signature with many (all?) kmods, I assume it applies for them all.

See output of dmesg below.

 

Edit: Wanted to say - I can't tell if these are 2 distinct errors, so I posted both together

 

Thanks

clarification

I think stack trace and the other error is not related. Stack trace probably stems from some display error, simple framebuffer thing. It may help to share DTS.

 

I know this is not a bright idea but if you're able to compile your kernel, you can try disabling CONFIG_MODULE_SIG and/or alike for the sake of suppressing the error.

Thanks for the reply.

 

Now I see what you're talking about - it does seem like two seperate issues.

 

So perhaps I should focus on the kmod signatures:

I don't think I want to circumvent the problem - I would prefer that the modules pass the verification.

 

To me it seems that the kernel is misconfigured such that it does not have a certificate to match the autogenerated key used for kmod signing.

Is there a way for me to check this on-board?

It seems that BOTH problems are solved as of the 21.05.1 update.

 

Big thanks to the devlopers, and also to all who helped me.
