[U-Boot] U-boot hangs on boot time

[John Smith]

Hey all,
?
my u-boot-1.1.1 hangs while booting, as follow is the message got from the serial:
------------------------------------------------------
U-Boot 1.1.6 (Jan 5 2009 - 18:37:55)
DRAM:?? 8MB
Flash:???? 2MB
?
------------------------------------------------------
after some tests by tracing the sequences of the funtions, I found that the u-boot hangs while comming? to this funtion:
device_register (&dev),? which is a subfuntion? of drv_system_init (); 
and I look into device_register(&dev):
int device_register (device_t * dev)
{
 ListInsertItem (devlist, dev, LIST_END);
 return 0;
}
as follow are two invoid funtions copy from the devices.c.
int ListInsertItem (list_t list, void *ptrToItem, int itemPosition)
{
 return ListInsertItems (list, ptrToItem, itemPosition, 1);
}
int ListInsertItems (list_t list, void *ptrToItems, int firstItemPosition,
?????? int numItemsToInsert)
{
 int numItems = (*list)->numItems;

 if (firstItemPosition == numItems + 1)
? firstItemPosition = LIST_END;
 else if (firstItemPosition > numItems)
? return 0;

 if ((*list)->numItems >= (*list)->listSize) {
? if (!ExpandListSpace (list, -numItemsToInsert))
?? return 0;
 }

 if (firstItemPosition == LIST_START) {
? if (numItems == 0) {
?? /* special case for empty list */
?? firstItemPosition = LIST_END;
? } else {
?? firstItemPosition = 1;
? }
 }

 if (firstItemPosition == LIST_END) { /* add at the end of the list */
? if (ptrToItems)
?? memcpy (ITEMPTR (list, numItems), ptrToItems,
???? (*list)->itemSize * numItemsToInsert);
? else
?? memset (ITEMPTR (list, numItems), 0,
???? (*list)->itemSize * numItemsToInsert);

? (*list)->numItems += numItemsToInsert;
 } else {???? /* move part of list up to make room for new item */
? memmove (ITEMPTR (list, firstItemPosition - 1 + numItemsToInsert),
??? ITEMPTR (list, firstItemPosition - 1),
??? (numItems + 1 - firstItemPosition) * (*list)->itemSize);

? if (ptrToItems)
?? memmove (ITEMPTR (list, firstItemPosition - 1), ptrToItems,
????? (*list)->itemSize * numItemsToInsert);
? else
?? memset (ITEMPTR (list, firstItemPosition - 1), 0,
???? (*list)->itemSize * numItemsToInsert);

? (*list)->numItems += numItemsToInsert;
 }
 return 1;
}

Most strange thing is sometimes it runs very well.
My board is S3C44B0...
?
Any help is appreciated.
