[conspire] kernel crash reported // for wifi ?

[Ken Bernard]

Hi everyone -
I get an annoying message when ever I use Wifi on my* Centos 6, Lenovo
ThinkPad (T61*). I think I asked about this earlier this year, or late in
2010. Laptop uses Gnome, but can dual boot to Windows XP.

I got my Wifi to work, but I am sure that I did many things that Daniel G.
would not do. I got it to work by adding libraries and checking the
internet forums.

This is what I get besides the black box that says: Kernel Crash has
occurred.:


Crash Kernel Report -- to do with wireless drivers (I downloaded and
installed drivers to get wifi to work on installation)

comment

I tried many times and many ways to get MADwifi working
I tried to install ath5k also

I know I took a shotgun approach to getting wireless working

I created a file "/etc/hostapd.conf"
        file is cut and paste from <
http://madwifi-project.org/wiki/UserDocs/UsersGuideExamples >
                Scroll downb to: "Single AP with hostapd on an
Automatically Chosen Channel"

       I tried to run the " myprompt# wlanconfig ath create wlandev wifi0
wlanmode ap
        ath0 "  command but got error unrecognised

Wifii worked after reboot but with this Bug reported
this Bug report occurs from time to time when I use wifi (beyond first
time, most times I use wifi I get the Kernel Crash report, but not every
time I use a Wifi connection)

reproduce
-----
1. First time I was able to use wifi card -- but I also got this message
about kernel module crash
2. Was able to connect to internet with wireless-- even though I got this
message
3. Restart wireless after reboot??? should reproduce the crash message it,
does sometimes usually within 15 minutes, but I haven't deliberately tried
to reproduce this Bug.

should I just continue ignoring this message?

P.S. I am always planning to drop Rick's on CABAL Saturdays but I always
seem to  be too busy.
