Hmm, I misunderstood the issue. I don't think that was a reporting glitch (those are considerably more obvious), but instead the KMS screensaver kicked in and stopped updating the screen. Normally just pressing an arrow key or something will cause it to start updating again.

Reporting glitches look like when the output looks incomplete or corrupt and then it stops loading new data on screen. It's more obvious that it's a reporting glitch if you're seeing this in a Plymouth splash screen. If you're just seeing it print text output into KMS, then it may just be the display going to "sleep" improperly.

Also, to note, system upgrades in DNF are operated *entirely* from the original rpm + dnf version, so the Mageia 7 versions of the packages have no impact until the transaction is done (usually).

Source RPM: rpm-4.13.1-3.2.mga6, rpm-4.14.2.1-12.mga7, dnf => rpm-4.13.1-3.2.mga6
Version: 7 => 6

I did get the screen to reload, but it stopped at exactly the same spot instead of much further.

To me, it looked neither incomplete nor corrupt. There were only many duplicate lines (which is likely unrelated). I'll attach a picture from the "frozen" screen.

I doubt the display was trying to go to sleep, because this happened to me in cauldron too, but then after being logged in and while using "dnf distrosync". Xfce wasn't frozen, but the terminal in which I was running DNF stopped updating its output. pstree showed that DNF hadn't quit and after reboot I found there, too, that many, many more packages had been upgraded/installed than were in the file to which I had piped the DNF output.

Anyway, if that can still be caused by KMS, what should I add to the kernel parameters for the "Intel 810 and later" card on that laptop, to disable KMS? 

  nomodeset i915.modeset=0

?

So far, I haven't been able to reproduce this issue. For me, system upgrades actually complete as intended, and the text output shows up just fine continuously...

Mageia 6 is EOL.
