Warning Message for viostor drivers from windows

Hi Team,

We are running Windows machin on KVM hypervisor and found few machines are getting unresponsive -but do not fail - and the only way to get them running is to restart the VM. I checked windows logs and found a lot of Viostor Warning message as below.

Reset to device, \Device\RaidPort0, was issued Reset to device, \Device\RaidPort01, was issued

Can this cause the VM getting unresponsive. Below is the screenshot for the virtio drivers details.

Device PCI\VEN1AF4&DEV1001&SUBSYS00021AF4&REV00\3&13c0b0c5&0&20 was configured.
