Hi,

I recently noticed that my debian 10 VMs reports high disk usage (80-100%) with atop.
Here are some screenshots for the same vm (completely idle) ran by several pve kernels

Kernel 5.4.114

Kernel 5.4.106
1624544846356.png

Kernel 5.4.73
1624545136968.png

any ideas ?

Running some basics 'dd' tests writes inside the vm shows good writes performance in each situations...

Thanks in advance,

Antoine
