Bug Description

Constant pause & strange behavior with Kubuntu 20.04.1 daily 'live' qa-test.

Following has been pasted from http://iso.qa.ubuntu.com/qatracker/milestones/414/builds/218299/testcases/1303/results/
----

dell [optiplex] 755 (c2d-e6850, 5gb, amd/ati radeon rv516/x1300/x1550)

system appears stable (no led on thumb-drive so can't see IO from that device), but no panel, nothing is functional though, I can move mouse around, clicks don't do anything, not even on install kubuntu icon top left.

eventually it came good..
kubuntu@kubuntu:~$ ls -la /var/crash

firefox; stream local news in window, maximized, f11 & fullscreen, no issues
dolphin (plan was to navigate to my hdd & open some found files using installed apps, ... nope

it's paused again... been 2+ mins, firefox is still streaming news, but dolphin has outline borders for the window, and nothing else... middle of dolphin-window shows background... (terminal where I copy/pasted /var/crash detail here)..

I clicked dolphin at menu again, then nothing, wait another minute... (firefox keeps streaming news)...

I click on firefox & suddenly BOTH DOLPHIN windows appeared... does the issue relate to video card?? and my display isn't being updated????

i try and continue, using a dolphin window I can't find where to navigate to my hdd partitions, so open menu to 'mount' with KDE.Partition.Manager.. and menu freezes for ages...

something is up... i close menu, try again to open menu.
his time menu opens & kde partition manager is easily found, it starts & actually has now stopped with the window "Scanning device /dev/fd0" (scanning a floppy?????) I do have a floppy inserted b/c of recent calamares testing with floppies, but I don't expect it to be an issue...

try to take screenshot of :"Scanning device /dev/fd0" and it appears to work, now it's stopped again, "Unsaved* - Spectacle" border of window but contents now the background (I did drag it around which caused contents to be replaced by terminal which is underneath it... long delay.. system keep stopping for 20+ seconds (not timed, so very subjective..) The save dialog just appeared like others, eventually it comes good, but time enough for me to click on this page, and type 70% of this paragraph is too slow to be usable.

kde partition manager still scanning /dev/fd0

My intention is to abandon this test, it's ~ pointless/unusable
Go try out other machines, then I can return here.

After testing two other boxes, having a different issue on one, and a perfect test on the other - I re-tested this box.

Loading KDE Partition Manager caused floppy drive to start spinning, but it didn't remain at that "Scanning Device /dev/fd0" this time... it responded appropriately.

This re-test on the same box did NOT experience the issues reflected in this bug report.

Alas I forgot to upload here the screen pictures I took & mentioned in my comments on initial run.

Further as this report doesn't even contain `dmesg` output, it'll be of no value at all unless it occurs again.
It thus has to remain incomplete. (I should have checked what was uploaded)
