you installed Kubuntu after you installed Mageia.
the Kubuntu ubiquity / calamares installer saw your Mageia swap and formatted it.
By doing so it caused a new UUID to be generated for that partition.
So yes, Kubuntu doesnt mind that all the swap partitions it sees are correct UUID for its initrd.
How-ever, it is likely that re-installing Mageia will change the Mageia swap UUID, especially if you format it, and then your slow boot will transfer to Kubuntu.
For this reason, the Mageia installer will only format swap partitions "on demand" from the user.
I specifically used the manual install option and made sure that Mageia swap was not targeted for formatting, when installing. Soo, unless the Kubuntu installer screwed up, which it admittedly sometimes does, the Mageia swap was specifically not formatted when I installed Kubuntu. Anyway, bottom line... How do I sort out the fstab so that Mageia boots properly?

Hmm. I dug around in the /etc/fstab file and the swap UUID matches that of the actual partition as listed in Gparted, so that isn't the problem. I have checked the other entries as well against the UUIDs from Gparted. The offending entry in the /etcfstab is /devsda3, the Kubuntu swap partition UUID. The entry should be e61037a5-06f0-4e01-9bbb-ade94352c35. I still would like to know if this is correct and I should change the Kubuntu swap UUID...

OK, I corrected the /etc/fstab entry (I really hate mucking around in the fstab). Boot is a little bit quicker, but not fantastic...
