Description Michael J. Burns 2012-02-23 00:33:52 UTC 
Description of problem:
Kernel 3.2.2 and higher fails to make the r8187se device as wlan0.

Version-Release number of selected component (if applicable):
Kernel 3.2.2

How reproducible:
Highly

Steps to Reproduce:
1. Upgrade kernel from 3.2.1 to 3.2.2 or higher.
2. Reboot.
3.
  
Actual results:
No wlan0 interface is made.

Expected results:
Make the wlan0 interface.

Additional info:
"bringing up wlan0" is absent from dmesg. And wpa-supplicant fails in messages.
Comment 1 Josh Boyer 2012-02-23 01:14:48 UTC 
Can you post dmesg from both 3.2.1 and 3.2.2?

We've always CONFIG_R8187SE disabled in Fedora as far as I'm aware, so if you had the r8187se module loaded then it was outside of what Fedora ships.  As you can see, the 3.2.1-e and 3.2.2-1 kernels from koji both ship the rtl8187.ko driver, but not r8187se.

dmesg from kernel 3.1.0-7

This is dmesg from kernel 3.1.0-7 with kmod-staging. The wireless wlan0 is initialized.

dmesg from kernel 3.2.6-3

This does not initialize the wireless wlan0.
Comment 4 Michael J. Burns 2012-02-23 20:51:02 UTC 
Yes this installation includes kmod-staging from rpmfusion, the historical way of making this rtl8187se card work.

You should report this issue to rpmfusion.
