It looks the other calltrace has been resolved by some changes between next-20170203 and today. Here the kernel is trying to load the Hyper-V storage driver (hv_storvsc), and the driver's __init and .probe have finished successfully and then the kernel hangs here. I believe something is broken recently, because I don't have any issue before Jan 31. Thanks, -- Dexuan
