I must correct what I said earlier about the versions of RPis I have. Should have waited until get back home instead of I depending on the picture from the screen with the errors.
It took a bit of effort to check the version on actual hardware as all my 4 RPis are in Pi rack, so it's bit cramped and dusty now. So, checked it and my main testing device is RPi 3 model B v1.2, then tested booting Centos 8 twice really on RPIs 3 Model B+. Also have RPi 4 but for obvious reasons not even tried to boot Centos 8 on it.
Now, earlier I got the BCM number from the logs that were displayed when booting Cenots 8, which do seem to be correct? As I just checked both test devices that are running Centos 7: RPi3B and RPi3B+, and they report in /proc/cpuinfo:
3B+: Hardware: BCM2835 Revision: a020d3 Model: Raspberry Pi 3 Model B Plus Rev 1.3
3B: Hardware: BCM2835 Revision: a02082 Model: Raspberry Pi 3 Model B Rev 1.2
Thanks,
Marcin

BCM2835 is a red herring because ( as described at https://www.raspberrypi.org/documentation/hardware/raspberrypi/revision-code... ) , kernel 4.9+ reports BCM2835 for all chipsets. One must use the revision code in order to differentiate the real version of the SBC. In this case Marcin is right, rev. a020d3 stands for 3B+ and rev. a02082 stands for 3B

All,
I downloaded C8 Minimal image again (I think it's in fact 4th time when I re downloaded the image), wiped my "production" sd card and it works. Unbelievable that my other 2 sd cards worked fine with C7, did not work with C8. Might just throw those 2 away.
Anyway, thank you for your effort in making the image and sorry about the trouble I caused.
Regards,
Marcin
No problem, glad it worked! I've seen some SD cards with "short term" memory problems, they forget what you write and go back to what they had..... In your case, maybe writing c7 on top of c7 wasn't that different. I don't know crazy thought ;)
