DM365 IPNC software restart will hanging

Dear Sir,

   I have migrated to DM365 IPNC Ref Design v2.5, now I found if i continue to do 10 or 20 times softwar restart in the GUI  ,the uboot will boot error,  prompt info as below:

***************************************************************************************************************************************************************************

  I used u-boot-1.3.4-dm365_ipnc_1.0.1.bin,  UBL_DM365_NAND_IPNC.bin.  The above info is printed from "int EDMA_Read8(unsigned long src, unsigned long dst, int length)" in uboot project "/drivers/mtd/nand/nand_base.c", I guess maybe the EDMA init failed when reboot, 

This issue is same as the link

http://e2e.ti.com/support/embedded/f/354/p/91288/317632.aspx

For the DMA hanging . Except by the Power off/Power and through console to write the command ./killall.sh to do.

Have any other method to recover it ? Due to If the IP CAM is hanning in the remote site then we can not to power off/power on it or connect the RS232 to write the command.

Thanks your help.
