This is supposed to generate a GP fault (e.g. see page 2942 of https://software.intel.com/sites/default/files/managed/39/c5/325462 -sdm-vol-1-2abcd-3abcd.pdf). When running with KVM a fault did indeed occur, but when not specifying any acceleration, no fault occurred. Let me know if you need me to develop a minimum example to debug from. At the moment it's all part of a slightly more complicated bit of code. Version: 5.2.0 (compiled from source) Command line options: -smp cores=4 -m 8192 (plus whatever uefi-run adds to plug in OVMF and my UEFI application).
