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",
			(u32) stage->load, stage->memlen,
	memset((void *) (u32) stage->load, 0, stage->memlen);

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

Have a good weekend!
