[U-Boot] Hanging in kmalloc of nand_scan_tail() function

[J.Hwan.Kim]

Hi, everyone

I'm using U-boot 2009-03.
U-boot hangs in nand_init() function.
I found the routine kmalloc in nand_scan_tail() cause U-boot reset.


int nand_scan_tail(struct mtd_info *mtd)
{
    int i;
    struct nand_chip *chip = mtd->priv;

    if (!(chip->options & NAND_OWN_BUFFERS)) {
        chip->buffers = kmalloc(sizeof(*chip->buffers), GFP_KERNEL);   
    }

    if (!chip->buffers)
        return -ENOMEM;
              ........


U-boot displays message as follows :

NAND:  data abort
pc : [<31f902b4>]\0x09   lr : [<31fa084c>]

Resetting CPU ...


Where the malloc function is defined?
Why the kmalloc() hangs the u-boot?
Is there any configuation definition needed?

Thanks in advance.
