access nand flash and mmc card at the same time on xlp board, there will be many io errors and system will hung

[yzhu1]

Hi, Chris

I run a tests on a xlp208 board. This kernel is 3.17-rc5.
The script are as below.
-------------Begin-------------------
mkfs.ext3 /dev/mmcblk1p1
mount /dev/mmcblk1p1 /mnt
cd /mnt
cp -Rf /root/nand_sd_test /mnt
cd /mnt/nand_sd_test
-------------End---------------------

After several minutes, the following errors will appear.
Would you like give me some advice about this error?

Thanks a lot.
Zhu Yanjun
