In all of 2.6.26-rc1, rc2 and rc3, my iwl3945 wifi card can't associate with my access point. It does associate in 2.6.25. under 2.6.-26-rc[1,2,3] wpa_supplicant reports: Trying to associate with 00:16:e3:ef:5d:f0 (SSID='' freq=0 MHz) Authentication with 00:00:00:00:00:00 timed out. where under 2.6.25 I was associating with Trying to associate with 00:16:e3:ef:5d:f0 (SSID='SIEMENS-EF5DF0' freq=2437 MHz) Associated with 00:16:e3:ef:5d:f0 WPA: Key negotiation completed with 00:16:e3:ef:5d:f0 [PTK=CCMP GTK=CCMP] I tried bisecting, and I got as far as git-bisect good 4b119e21d0c66c22e8ca03df05d9de623d0eb50f git-bisect bad 96d510566e4908f77f03ff1436c78ae7162a17d0 but a point between these 2 commits gets me iwl driver that hangs kernel when it's loaded, so I gave up on bisecting at this point. Still this leaves us with 91 candidates that might be introducing the regression (get their list with git log 4b119e21d0c66c22e8ca03df05d9de623d0eb50f..96d510566e4908f77f03ff1436c78ae7162a17d0) Additional info: I get this in dmesg [ 99.153033] ACPI: PCI Interrupt 0000:03:00.0[A] -> GSI 17 (level, low) -> IRQ 17 [ 99.204031] PM: Adding info for No Bus:iwl-phy1:radio [ 99.204031] Registered led device: iwl-phy1:radio [ 99.204031] PM: Adding info for No Bus:iwl-phy1:assoc [ 99.204031] Registered led device: iwl-phy1:assoc [ 99.204031] PM: Adding info for No Bus:iwl-phy1:RX [ 99.204031] Registered led device: iwl-phy1:RX [ 99.204031] PM: Adding info for No Bus:iwl-phy1:TX [ 99.204031] Registered led device: iwl-phy1:TX [ 99.220405] ADDRCONF(NETDEV_UP): wlan0: link is not ready and even though the led now lights up, there's no association. portions of .config: 2.6.26-rc3: CONFIG_IWLWIFI=m CONFIG_IWLCORE=m # CONFIG_IWLWIFI_LEDS is not set CONFIG_IWLWIFI_RFKILL=y # CONFIG_IWL4965 is not set CONFIG_IWL3945=m CONFIG_IWL3945_SPECTRUM_MEASUREMENT=y CONFIG_IWL3945_LEDS=y CONFIG_IWL3945_DEBUG=y 2.6.25: # CONFIG_IWL4965 is not set CONFIG_IWL3945=m CONFIG_IWL3945_QOS=y CONFIG_IWL3945_SPECTRUM_MEASUREMENT=y CONFIG_IWL3945_DEBUG=y What kind of additional information would be useful for debugging this regression?
