Ha, I thought kvm was on by default. Apparently not, qemu -enable-kvm avoids this issue.
Yes, 0x0000000100000000 with RIP=00000000ffffffe4 is quite suspicious, especially after the splash screen has been displayed. Off in the weeds comes to mind - so I'm guessing corrupted or incorrectly mapped guest memory? The git tree is where? (I just grabbed the tarball)
