IMX23 usb instability on 3.9-rc5

[Alexandre Pereira da Silva]

Hello,

I am testing a usb key connected on a IMX23-Olinuxino board. The
kernel panics at heavy usb trafic. This was build with the mxs
defconfig

This happens everytime with "dd if=/dev/sda of=/dev/null bs=4k". The
messages of the failure varies a lot from run to run.

I tested also on kernel version 3.7.10 and the results are the same.

Please let me know if you need any more details.

Here its the panic messages:
# dd if=/dev/sda of=/dev/null bs=4k
