Hello, recently I`ve got a couple of shiny new Intel 2620v2s for future replacement of the E5-2620v1, but I experienced relatively many events with emulation errors, all traces looks simular to the one below. I am running qemu-2.1 on x86 on top of 3.10 branch for testing purposes but can switch to some other versions if necessary. Most of crashes happened during reboot cycle or at the end of ACPI-based shutdown action, if this can help. I have zero clues of what can introduce such a mess inside same processor family using identical software, as 2620v1 has no simular problem ever. Please let me know if there can be some side measures for making entire story more clear. Thanks! KVM internal error.
