--- Comment #5 from Quentin Thébault <quentin.thebault@defenso.fr> ---
Happened to me with a slightly different instruction sequence:

```
bhyve: tpm_crb_mem_handler: cancelling a TPM command is not implemented yet
bhyve: tpm_crb_mem_handler: invalid write @         fed40464 [size = 4]
Failed to emulate instruction sequence [ 8901f044092c244883c2044883c104 ] at
0xfffff800711bbb42
```

This is on a running Windows 11 guest with swtpm emulated TPM, not
pass-through.
