Some quick comments: 1. hyperv_vmbus_probe() assumes the existence of the PCI device, which is not true in a Hyper-V Generation-2 VM. 2. It looks some other functionality in the hyperv_fb driver has not been implemented in this new driver either, e.g. the handling of the SYNTHVID_FEATURE_CHANGE msg. Thanks, -- Dexuan
