Subject: [PATCH 0/3] Drivers: hv: fix kdump (again) and more
Date: Mon, 18 Jan 2016 18:18:36 +0100 [thread overview]
Message-ID: <1453137519-20304-1-git-send-email-vkuznets@redhat.com> (raw)
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
