[Qemu-devel] E5-2620v2 - emulation stop error

[Andrey Korolyov]

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!
