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

[terry]

Dear everyone,
I'm using u-boot-2010.09. After I download u-boot.bin to my boards(cpu
is s3c2410),the output from serial shows that cpu has exception, the
information list as following:
U-Boot 2010.09 (Nov 11 2010 - 21:55:07)

U-Boot code: 33F80000 -> 33FA0BDC  BSS: -> 33FA45EC
RAM Configuration:
Bank #0: 30000000 64 MiB
NAND:  data abort
pc : [<33f8fbb4>]          lr : [<33f85f70>]
sp : 33f07fac  ip : 00000000     fp : 00000000
r10: 00001298  r9 : ffffff7f     r8 : 33f4ffe0
r7 : 00000000  r6 : 33fa3b50     r5 : 33fa3c00  r4 : 33fa0274

Flags: NzCv  IRQs off  FIQs off  Mode SVC_32
Resetting CPU ...

value of pc locate at <malloc> function, value of lr locate at
<nand_scan_tail>(/drivers/mtd/nand/nand_base.c).

I have seen that someone had this problem before, have you resolved it?
Can you give me some suggestions?
