Hi over the past few months I've seen a strange behaviour on my Fedora 30 KDE. I see processes accessing the disk for very long periods totally blocking the user interface. I've seen SpiderOakONE, dnf and rpm on the process list. Is this a SSD problem? Is the disk worn out? Or is it a deliberate behaviour in the kernel drivers that has been introduced in the last quarter of 2019? I hope someone can point me where to search for more evidence for what i the root cause of the annoying problem, that renders my laptop almost useless for periods. |< -- Med venlig hilsen Klaus Kolle Teknikumingeniør, B.Sc.EE., e-mail : klaus(a)kolle.dk Master of IT www : www.kolle.dk Asger Jorns Vej 17 Telephone : +4522216044 DK-8600 Silkeborg, Denmark "Man skal ikke tilskrive til sammensværgelser hvad der tilstrækkeligt kan forklares af inkompetence" Poul Henning Kamp Planlægning er tanker om noget man agter at gøre en gang i fremtiden, hvis omstændighederne tillader det.

Yes it looks much like the bug reported back in September - and that somebody have found a fix to already. Just annoying that it hasn't made its way into the Fedora kernel.

I see it right now. I decided to upgrade to 31 from 30. And the activity writing all the downloaded modules really interrupts the user interface from being updated. Lets see if it runs better under 31.

I did some search a while ago and found this bug as fixed in upstream. However the kernel we now have in Fedora 30+ should be already the one containing fix for this, which means it's not fixed at all or it's a different issue. I myself experience this while I have setup with external monitors attached to my laptop. Using just my laptop I don't seem to experience this at all or that much.
