This is quite a few months out of date and there have been many bug
fixes since then.  Please upgrade to linux-image-3.2.0-0.bpo.4-amd64
version 3.2.35-2~bpo60+1 and report whether the bug remains.

A fairly clear memory leak, but sadly it's not obvious what is leaking.

Please send the output of:
- lsmod
- lspci
- dmesg
