Comment 17 for bug 585938

Zach, sorry for the delay. so far no real help from realtek though they are at least responding, and I think they want to help. I'm attaching the tarball they sent me with a new version -- it makes no difference to me but might make some difference to others. They say they can't reproduce the bug with powertop, though that seems unlikely to me. Anyway I have asked them to subscribe to this bug and am also writing to the powertop list asking for pointers... this is pretty frustrating but maybe it will eventually get resolved.

Here are the instructions they sent me:

Please find the latest RTL8191SE Linux driver source in the attachment and
try again.
You should clear previous drive or inbox driver first after you install this
driver source.
The previous driver will be stored within
/lib/modules/2.6.XXX/kernel/driver/staging.
Please remove "r8192se_pci.ko" files by following command.
1. sudo su (you should input you root password after it)
2. find /lib/modules/ -name "r8192se_*.ko" -exec ls -l {} \;
3. find /lib/modules/ -name "r8192se_*.ko" -exec rm {} \;

After, You could execute "find /lib/modules/ -name "r8192se_*.ko" -exec ls -l {} \;" to confirm it's clear properly.
And then, install this driver source as below steps. Don't forget to extract
this package before you install it.
1. sudo su
2. make
3. make install
4. reboot
5. ./wlan0up or ./wlan1up

---------------------

they also suggested installing the new firmware before building the module -- this is easy, just move the old /lib/firmware/RTL8192SE folder somewhere safe, and replace it with the firmware/RTL8192SE folder you find in the tarball after extraction.

hope that helps..
