OS rebooting does not proceed after nv-hostengine is 100% used

hello.

OS rebooting does not proceed after nv-hostengine is 100% used.

After installing ubuntu 20.04, the GPU driver and datacenter-gpu-manager tool were installed and operated.

After a few days, rebooting of the system did not proceed, and when I checked the top, the usage of nv-hostengine was 100% as shown in the screenshot above.

Could the nv-hostengine damon be the cause? Or is there some other cause?

If anyone knows about this issue, please reply.

Looking at the time nv-hostengine consumed, it seems it’s been running all days at 100% so there definitely something wrong with it.
