Kdump on crash is reportedly broken for Hyper-V guests and I was able to
find two reasons:
1) Inability to boot with nr_cpus=1 (PATCH 1)
2) Sleeping in interrupt context on crash (PATCH 2 and 3)
Vitaly Kuznetsov (3):
Drivers: hv: vmbus: avoid infinite loop in init_vp_index()
Drivers: hv: vmbus: avoid scheduling in interrupt context in
vmbus_initiate_unload()
Drivers: hv: vmbus: don't manipulate with clocksources on crash
