Is that a standard (non-realtime) kernel? If not, can you also test a
standard kernel configuration (linux-image-3.2.0-3-amd64)?

Probably not!
Please try booting with the extra kernel parameters:
memory_corruption_check=1 memory_corruption_check_size=640K
memory_corruption_check_period=5
Does that avoid the problem, and if so what does the kernel log show
after you plug in the device?
