(In reply to Konstantin Belousov from comment #26)

I am on stable/12, so I added
    if (cpu_maxphysaddr > VM_MAXUSER_ADDRESS)
            cpu_maxphysaddr = VM_MAXUSER_ADDRESS;

(I also needed #include <vm/pmap.h> and #include <machine/vmparam.h>.)

Now I am back to the original error:

wrmsr to register 0xc0011029(0x3) on vcpu 0
rdmsr to register 0xc00000e9 on vcpu 0
Unhandled ps2 mouse command 0xe1
Unhandled ps2 mouse command 0x88
Assertion failed: (pi->pi_bar[baridx].type == PCIBAR_IO), function
passthru_write, file /usr/src/usr.sbin/bhyve/pci_passthru.c, line 916.
