Hi David,
The OS is hitting something undefined. It's built on exploiting the x86
architecture to run computations of the MMU rather than the CPU:

I've tried it on the 3 most recent versions of QEMU for Windows. I'll give it a
go with KVM and tcg and get back to you although I'm not hopeful.

Title:
0x8 exception encountered but not handled
Status in QEMU:
Incomplete
Bug description:
Present in all QEMU versions.
OS is triple page faulting and crashing rather than handling the
expected double page fault properly. The same OS works in Bochs so I
know its not the problem.
