Thanks for the quick response, Reco.
1. Kernel is stock wheezy:
3.2.0-4-amd64 #1 SMP Debian 3.2.57-3+deb7u2 x86_64 GNU/Linux
2. I don't know when 3.2.0-4 was released; I suspect the answer is yes.
3. many reboots; the last one earlier today.
I note bug=767836 describes this problem, but appears closed with 3.2.0-4
