Default Bug#512255: linux-image-2.6.26-1-amd64: #512255 - possibile patch

tags 512255 fixed-upstream
thanks

*Driver*
iwl3945

*Problem*
The physical button on the keyboard to enable/disable wi-fi doesn't work properly.

case1: start with wireless ON -> button pressed -> wireless OFF -> button pressed (again) -> nothing (wireless still OFF) (+ kernel oops) -> rmmod iwl3945 & modprobe iwl3945 -> wireless ON

case2: start with wireless OFF -> button pressed -> wireless still OFF (+ kernel oops) -> rmmod iwl3945 & modprobe iwl3945 -> wireless ON

"modprobe iwl3945 debug=0x43fff" doesn't produce any additional useful output on dmesg, even if I recompile the kernel with CONFIG_IWL3945_DEBUG=y.

Please see all the history of this bug report for more details:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=512255.

*Tests*
1) ubuntu (just to compare), linux 2.6.24: everything works
2) linux 2.6.26 (debian sources): problem described above
3) linux 2.6.26 (debian sources + latest compat wireless): OK!
4) linux 2.6.26.8 (vanilla): same problems
5) linux 2.6.26 (orig.tar.gz, taken from debian ftp): same problems
6) linux 2.6.28.4 (vanilla, latest stable): OK!

*Conclusions & solution*
It seems a problem affecting also upstream, but it solved with latest version of the driver and/or kernel.
Looking and the date of the source code of compat-wireless_old I discovered that the iwl3945 was modified the last time in the middle of September 2008, then it can be considered well tested and so stable.

Could you update the iwl3945 driver with the "latest" (September 2008) provided by compat-wireless_old?
http://wireless.kernel.org/download/compat-wireless-2.6/compat-wireless-old.tar.bz2
It should not be so difficult to do (but I'm not a kernel hacker and so I can't be totally sure).

Another possibility is to provide an extra package with newer (and better) drivers, but in my humble opinion it's more difficult to do and obviously not so useful for upcoming lenny (release team won't accept new packages).

It's VERY annoying to do rmmod & modproble every time a person would like to enable/disable wireless and, of course, it isn't absolutely a friendly approach for a non-expert user.
I (and probably many other people with same wi-fi card) will be happier if you update the driver, solving this bug.

Regards,
Alberto

Just one more thing probably not so clear.
I spoke about compat-wireless_old because only "_old" supports linux <= 2.6.26.
Newer versions only supports >= 2.6.27.

P.S.: sorry, I forget word-wrap in previuos email.
