I'm not seeing anything odd there.
It does feel like CPU state corruption - either due to a qemu bug, or due to some odd trap/interrupt handling bug of ours.
Or possibly a CPU/microcode bug. You wouldn't happen to run this on an AMD Piledriver-based CPU with the 0x06000832 microcode?
Because we do have a pending qemu-related bug-report that turned out to be a AMD microcode problem with NMI delivery. Looking at that bug report, it actually looks rather similar - also due to a confused RIP.
