Subject: iwl3945 not working properly.

Hello,

I have a Toshiba Satellite A135-S4427 with and Intel 3945ABG card, the
driver is not working properly.

When I turn on my PC it works fine, but If I ever bring the interface
down, I no longer can associate it with any AP without rebooting, even
the one I was using, I tried rmmod/modprobe iwl3945, didn't do
anything,

iwconfig shows that the wlan0 has the radio turned off, and

$ cat /sys/bus/pci/drivers/iwl3945/0000:04:00.0/rf_kill
1

Even If I echo 0 > /sys/bus/pci/drivers/iwl3945/0000:04:00.0/rf_kill
whenever I try to associate the interface with an AP it turns back to
1, I tried both iwconfig and NetworkManager, same problem.

There's a button on my laptop for Radio SoftKill (fn+F8) but it's not
working, the soft kill is being enabled/disabled without my
interference.

I tried it on kernel-2.6.24 and kernel-2.6.25-rc2 same result...

Any help is appreciated...

P.S: Please Cc to me, I am not subscribed to the mailing list.

This sounds similar to the bug here:

https://bugzilla.redhat.com/show_bug.cgi?id=432264

The OP in that bug reports that the problem continues even after
reverting to older kernels that worked previously.

Hopefully part of the Intel crew will have some clue as to what is
happending here?

Wael,

Could you please help us debug this issue? Unfortunately none of the
bugs reported about this issue
(http://bughost.org/bugzilla/show_bug.cgi?id=1454 and
https://bugzilla.redhat.com/show_bug.cgi?id=432264) have any debugging
output. Please reopen bug
http://bughost.org/bugzilla/show_bug.cgi?id=1454 and add debugging
(loading module with debug=0x43fff) to your report to help us find out
what happens on your system when the driver loads as well as when you
change the rfkill settings.

Thank you very much

Reinette

Reinette,

Since the problem I am having is slightly different than the bugs
above, I'm not sure I should post the debug there but feel free to
post it if you think it is the same...

Anyway, here attached is the debugging file, I hope this helps,
because it's so annoying, I had to reboot my laptop is order to send
this message...

Regards,
