This is on latest master branch on kvm.git and qemu-kvm.git, running

seeing this.

vmx_vcpu_run+0x26d/0x64f [kvm_intel]
Can you run this through objdump or gdb to see what source this
corresponds to?
Somewhere here I think (?)
objdump -d
Look at the address where vmx_vcpu_run starts, add 0x26d, and show the
surrounding code.
Thinking about it, it probably _is_ what you showed, due to module page
alignment. But please verify this; I can't reconcile the fault address
(ffffffff9fe9a2b) with %rsp at the time of the fault.

I have a truly marvellous patch that fixes the bug which this
