Bug#644362: This problem still exists in default wheezy kernel
I can indeed confirm that this problem is still present in the current
wheezy kernel:
ii linux-image-3.2.0-4-686-pae 3.2.46-1 Linux 3.2 for modern PCs
The stacktrace also looks simular:

I did apply the same patch as I applied to 2.6.39 and the patch still works.
