Thank you tglx for the comments and suggestions, which I think are reasonable. I realized this patch is problematic. The good news is that the LAPIC emulation bug has been fixed in the latest version of Hyper-V and now kdump can work reliably. I think the hypervisor fix would be backported to old Hyper-V versions, so hopefully this won't be an issue over time.
Thanks, -- Dexuan
