Subject: [REGRESSION] [IWL3945] Broadcast is broken?

Hardware:
08:00.0 Network controller: Intel Corporation PRO/Wireless 3945ABG [Golan]
Network Connection (rev 02)

Last known good kernel: 2.6.34

Failing kernels: since 2.6.35-rc1 to 2.6.35-rc3

Symptoms:
During connect do wireless network authentication seems be OK, but I cannot
get IP from dhcp serwer. I do:
echo 0x43fff > /sys/class/net/wlan0/device/debug_level

Syslog is here:
http://unixy.pl/maciek/download/kernel/2.6.35-rc3/gumis/syslog-before.txt

>From syslog I guess the problem is that it doesn't receive broadcast frames
(but I'm not sure), so I try:
sudo ifconfig wlan0 promisc

Syslog:
http://unixy.pl/maciek/download/kernel/2.6.35-rc3/gumis/syslog-after.txt

And then I can get IP address.

Any advice?

Regards

Very likely commit 3474ad635db371b0d8d0ee40086f15d223d5b6a4,
because I have same problem.

Try to revert it.
