Hmm, I wouldn't suspect any of those, but can you see if you still get the message without them?

Yes, the message is stil present after uninstall of all dkms modules. Full dmesg.log after fresh boot is in attachment.
May it be the result of latest patch for CPU's bugs?
   dmesg.log (61.4 KiB)
   cpuinfo.txt (4.7 KiB)
