Bug#745137: linux-image-3.2.0-4-amd64: Crash when trying to enable RTL8188CE-based WiFi interface on Lenovo ThinkPad W520
Hello Ben,
Thank you for uploading the fixed version. The following is mostly for
you information. (I.e. I do not expect you to do any additional
investigation. Neither am I going to spend more time on this.)

The interesting thing is that I do not see the regression in 3.2.57-3,
although it uses the same rtl8192ce patch as I was testing with. So, I
wonder if I missed some important step, or 3.2.57-3 contains a bit
more changes than just the patch? (Note that I also removed 3.10
kernel-related packages from the system before installing 3.2.57-3,
but this hardly could cause such change in behavior.)

And there are no "direct probe" messages in 3.2.57-3 log that were
failing in 3.2.57-2 + rtl8192ce patch.
P.S.
Found one case with "direct probe" failures magically solved on a
different hardware after rebooting to Windows -
