Had this again 20 minutes ago. Was dopying 8.7GiB of data from one directory to another directory on the same filesystem (ext4 (rw,relatime,data=ordered)) on the same disk (Western Digital WDC WD30EZRX-00D8PB0 spinning metal disk).
The KDE UI became unresponsive (Everything other than /home and user data in on a SSD), could not launch any new applications. Opening a new tab on Firefox to go to Youtube didnt load the page, and kept saying waiting for youtube.com in the status bar (network gets halted?). dmesg shows these, are they important?
