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.
