/dev/kfd unusable after gpu detach

Brief summary of the problem:

After detaching gpu with echo "0000:03:00.0" > /sys/bus/pci/drivers/amdgpu/unbind and trying to to use rocminfo for example, it returns error Unable to open /dev/kfd read-write: Invalid argument.

I have also integrated gpu so it should return something. Rebinding the gpu doesn't help.
