Bug#681232: linux-image-3.2.0-3-amd64: Atheros WiFi Adapter couldn't find networks "gain calibration timeout"
I have this same issue with linux-image-3.2.0.3-amd64 (3.2.21). All
previous wheezy kernels up to linux-image-3.2.0.2-amd64 (3.2.20) have
been working fine for me.

The fix of adding pcie_aspm=force to the kernel command line (see
message #124) seems to be working for me.
