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 [ 83.490000] Unable to handle kernel paging request at virtual address be7a170c [ 83.490000] pgd = c2b54000 [ 83.490000] [be7a170c]
