Package: makedumpfile Version: 1:1.5.9-5 Severity: important Tags: patch Hi, to use kdump on Hyper-V hypervisors, an ata_piix option needs to be passed otherwise the kdump kernel will attempt - and fail - to connect to the Hyper-V hypervisor service, which refuses to accept a second connection from any given VM.
