[LinuxBIOS] Unexpected Exception: 13

[michal wan]

in the file src/cpu/amd/model_lx/model_lx_init.c

static void model_lx_init(device_t dev)
{
       printk_debug("model_lx_init\n");

/* Turn on caching if we haven't already */

x86_enable_cache();

/* Enable the local cpu apics */
       //setup_lapic();

// do VSA late init
       vsm_end_post_smi();

// Set gate A20 (legacy vsm disables it in late init)
       printk_debug("A20 (0x92): %d\n",inb(0x92));
       outb(0x02,0x92);
       printk_debug("A20 (0x92): %d\n",inb(0x92));

printk_debug("model_lx_init DONE\n");
};
~
when using vsm_end_post_smi() function, Unexpected Exception occures, any 
advice would be appreciated!
