Subject: iwl3945 bug in 2.6.34

hello,

I am running a custom compiled 2.6.34 (fedora 12) on a hp nx7400 with
a Intel Pro Wireless 3945 card, the card works fine and connects to a
WEP secure wireless connection on my router. But after some time
network manager starts reporting that the wireless access point is not
available anymore and tries to reconnect to the network, though the
network is still available, it fails to detect the network , I have
not been able to reproduce the situation conclusively, seems to be
happening randomly ... here is the tail from "dmesg" which looked
suspicious :
(btw, I also faced the same problem earlier when I was running RHEL
beta 6.0 on the same machine)

No probe response from AP 00:1b:da:2a:a1:53 after 500ms, disconnecting.

how can this be fixed ? I need to reboot the machine every time this happens,
please let me know if any other information is needed .

This did not use to be an issue with 3945 and unfortunately we do not
know what is triggering it now. Please try the "Enable stuck queue
detection on 3945" patch that is attached to
http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=1834 as a
workaround.

Actually, sorry, but that patch will not work on 2.6.34 since the
feature it enables is not present there - it will be in 2.6.35 though.
To enable the feature in 2.6.34 will take some more backporting effort
that I'm looking into now.

Are you only experiencing this issue w/ a 2.6.34 kernel? Or also
with Fedora-provided kernels? If the latter, please be sure to open
a bug at bugzilla.redhat.com and Cc: [email protected] when you do.

This looks like the firmware died. Since this is iwl3945, you might
try a patch like Reinette suggests here:

Does that enable the device to recover?
