https://github.com/collectd/collectd/issues/2951 -> Could that be the problem?
Is there someone who has the same issue?

Yepp, same here.
No more Disk I/O since second half of January 19. Neither for raid nor nvme drive.
Only NaN Values arr being displayed and I today I got a monit alert: Does not exists collectd, restart, process is not running

Edit – just a quick note:
To verify FJW's hint I tried downgrading to kernel 4.18 (backport) - the result are as expected: Disk I/O starts to work again but since VirtualBoxes and Plex won't start anymore this doesn't even count as a workaround.
Seems like I'll have to wait for an updated collectd package.
