Hello,
with current IPXe, which has also commit
71560d185475117b10994d839afe059577e7768c:
[librm] Preserve FPU, MMX and SSE state across calls to virt_call(),
I can't boot on some servers. One of them is an HP server, but looks
like qemu virtualization is affected too. Tested with CentOS 7 and
it's qemu-1.5.3 and also qemu-kvm-ev-2.3.0. Both of them crashes on ipxe
startup with this message in logs:

qemu: terminating on signal 15 from pid 1183
2016-10-17 10:44:21.710+0000: shutting down
After revert of this commit everything works well.
I have just problems with this commit. Any chance to get it out or fix
these problems?
Regards.
