did the following:

# cat /var/log/messages |grep -i Invalid

Jun 30 10:17:30 praktifix kernel: [   24.198033] Invalid pltconfig,

But that does not relate to your error.

# cat /var/log/messages |grep -i random
Jun 30 08:54:00 praktifix kernel: [    0.228092] random: crng done

Jun 30 10:25:53 praktifix kernel: [  527.540354] r8168 0000:02:00.0
(unnamed net_device) (uninitialized): Random ether addr 82:c2:81:10:6b:c2

The last one probably results from my testing with r8169. The compiled
r8168 went online later. That also is the only message I found.

Thank you for your help in debugging.

Regards and greetings from Hamburg,
Karsten
