I wait for about 15-20 min and nothing special. I put some 'postcode'
functions for debug capability and I've found out that it hangs on
'cbfs_load_stage' function when it calls cbfs_find_file:

---------[ lib/cbfs.c ]--------
// ...

void * cbfs_load_stage(const char *name)
{
    struct cbfs_stage *stage = (struct cbfs_stage *)
    	cbfs_find_file(name, CBFS_TYPE_STAGE);
    /* this is a mess. There is no ntohll. */
    /* for now, assume compatible byte order until we solve this. */
    u32 entry;

outb(0xaa, 0x80);        // <--------------- It doesn't occur

if (stage == NULL)
    	return (void *) -1;

printk_info("Stage: loading %s @ 0x%x (%d bytes), entry @ 0x%llx\n",
    		name,
    		(u32) stage->load, stage->memlen,
    		stage->entry);
    memset((void *) (u32) stage->load, 0, stage->memlen);

if (cbfs_decompress(stage->compression,
    		     ((unsigned char *) stage) +
    		     sizeof(struct cbfs_stage),
    		     (void *) (u32) stage->load,
    		     stage->len))
    	return (void *) -1;

printk_debug("Stage: done loading.\n");

entry = stage->entry;
    // entry = ntohl((u32) stage->entry);

return (void *) entry;
}

// ...
---------------------------------------------------

On Monday I will test the cbfs_find_file function. I hope I will found
something.

Have a good weekend!
