Hi,
I hope I'm writing to the right addresses, this is my first kernel bug
report :-)
I regulary build linus' tree from git. One day, my wireless card was
unable to connect to the access point. dmesg showed something like this:
[ 122.290949] wlan0: direct probe to 00:15:0c:xx:xx:xx (try 1)
[ 122.490158] wlan0: direct probe to 00:15:0c:xx:xx:xx (try 2)
[ 122.690057] wlan0: direct probe to 00:15:0c:xx:xx:xx (try 3)
[ 122.890031] wlan0: direct probe to 00:15:0c:xx:xx:xx timed out
At first, I thought is was some link quality problem and tried it next
to the access point, but it still didn't work.
I booted another (older) kernel and with this one, the card was able to
connect without any problems.
I bisected the problem and came to commit
062bee448bd539580ef9f64efe50fdfe04eeb103
iwlwifi: set TX_CMD_FLAG_PROT_REQUIRE_MSK in tx_flag
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=062bee448bd539580ef9f64efe50fdfe04eeb103
My wireless card is a Intel Corporation Wireless WiFi Link 5100.
Will provide more info if needed.
Florian
PS: Please CC me, i'm not on linux-wireless.

Could you try different channel instead of channel 12 to see if the
problem still there?

That'd only happen _after_ association, not before, and assoc fails
here.

Hi,
I did a dmesg with 2.6.35-rc5 and debug=0x43fff.
You can get it here: http://pastebin.com/Q6eCdPZR

based on the log sent by Florian, I did not see bss_info_change with
current BSSID from mac80211. any thought?
I am expected to see something like this,
[165796.572969] ieee80211 phy3: U iwl_bss_info_changed changes =
0xFD
[165796.572972] ieee80211 phy3: U iwl_bss_info_changed BSSID
00:25:9c:d0:9f:e1
[165796.572976] ieee80211 phy3: U iwl_bss_info_changed ERP_PREAMBLE 1
