Bug#702770: linux-image-3.2.0-4-amd64: non-fatal oops while dd'ing from USB to USB
I got another non-fatal Oops (attached), this time in a simpler
situation. Before, I was reading a disk image (from a USB port) and
writing on an ext2 filesystem (on another USB port).
This time I first read the disk image without problems on the internal
disk, and the Oops happened when copying the image to the USB
filesystem. The image is 500 GB long and it stopped after writing
288006127616 bytes (this is the length I see with ls -l) on the
USB-mounted partition.
Here is the Oops:
