Still not solved.
Bug happens on Fresh install of Kubuntu 21.04 with reccomended HDD distribution on modern Lapotp (Ryzen5, 5500U).
And on older Laptop (~2014) with Ubuntu 20.04 & 21.04, Kubuntu 21.04 and Lubuntu 20.04 & 20.10 & 21.04. (experienced often, sometimes every few hours) Kswapd0 process rapidly increases in CPU then uses all resources (no result after hours) necessating reboot.
Killing a high Ram process (in the few seconds till all CPU is taken) (p.e. Firefox) stops the Kswapd0 process.
Am willing to provide additional data / reformat old laptop for tests etc.
