Bug#482337: linux-image-2.6.24-1-amd64: rfkill switch doesn't work with iwl4965 driver
 
Package: linux-image-2.6.24-1-amd64
Version: 2.6.24-6
Severity: important

The rfkill switch doesn't work, so I can't use my iwl4965 card. It's
strange because my Debian system doesn't work also with a custom Vanilla kernel (2.6.25-4) that
I've prevously used on Etch (while now I've installed Lenny from
scratch) and that did work on that system. And this kernel worked also
after a migration of the Etch machine to Lenny (updating the sources.list for the migration), so it seems
not to be stricly related to the Kernel (it worked for me).
I've tried using different versions of firmware (the one included in the
"non-free" branch and all others downloaded from Intel web site), but
nothing happened.
I'm using successfully this card with other Distros (kernel 2.6.24)
This is my lsmod:

iwl4965 198772 0

r8169 28164 0
backlight 6600 1 asus_acpi

And...

cat /sys/bus/pci/devices/*/rf_kill
2

So it is disabled. Note that the switch is phisically at the "RFKILL
OFF" position.

Thank you

unstable has a newer kernel try it out installs just fine in
testing.

Sorry,
I've tried with the latest SID kernel, but it didn't fix the problem.
The strange thing is that the Vanilla Kernel I'm using has had no problems on another system and on Etch and on that Etch upgraded to Sid (dist-upgrade).
I honestly think that it isn't a Kernel problem, but a configuration one.
Another kernel (2.6.22-3) works on my PC, but it's installed on a Ubuntu system I've installed to try using the wireless card.
Thank you

well rfkill switch is not that critical, but it just works here on my
x61s test box.
so no idea right now what is going wrong on your box.

ok, I've found the problem... it seems to be the acpid daemon.
I've found a workaround to use the card, which is:

1) stop the acpid
2) turn on the wireless card with keyboard shortcut provided by my laptop (fn+F2)
3) ifconfig wlan0 up

And now, all starts working!!!
Obviously, if I don't stop the acpid, it doesn't work (watching the wifi LED, when I press fn+F2 with acpid started, it turns on and immediately returns off, but without kernel messages!).
Is it an ACPI bug? Or a configuration one?
I've previously tried to disable ACPI at kernel boot time, but without no success.
Thank you
