Public bug reported:
When running lshw the VM sits scanning SCSI for a full minute. At the
same time CPUs show 100% usage. This appears to happen on all 4.4 kernel
versions running as virtual machines on Hyper-V even with the latest
integration services. This did not happen on earlier kernel versions.
