Thank you, @Werner. I've already left my house, but I'll quickly check the kernel config in `/boot` as soon as I get home. Just for my understanding, if the mentioned module is not marked as M there, the next step would be to re-compile the kernel, correct? If it is marked as M, do you have any further recommendations?
And @schwar3kat, I appreciate you taking the time to look into this. Yes, as seen in the previous screenshot, compiling the kernel took around 2 hours for me. It's kind of you to offer your assistance despite not having my board or familiarity with the Rados block device.
