I compiled with CONFIG_IWLWIFI_DEBUG. I also absent mindedly enabled CONFIG_IWLWIFI_DEBUG_EXPERIMENTAL_UCODE--please let me know if you do not want this. I can provide other debugging output, but I am sending this now in case I cannot respond promptly. # echo 0xFFFFFFFF > /sys/module/iwlwifi/parameters/debug # dmesg | grep iwl [ 10.116748] iwlwifi 0000:03:00.0: irq 43 for MSI/MSI-X [ 10.234866] iwlwifi 0000:03:00.0: loaded firmware version 18.168.6.1 [ 10.362940] iwlwifi 0000:03:00.0: CONFIG_IWLWIFI_DEBUG enabled [ 10.362952] iwlwifi 0000:03:00.0: CONFIG_IWLWIFI_DEBUGFS disabled [ 10.362957] iwlwifi 0000:03:00.0: CONFIG_IWLWIFI_DEVICE_TRACING enabled [ 10.362963] iwlwifi 0000:03:00.0: CONFIG_IWLWIFI_DEVICE_TESTMODE disabled [ 10.362967] iwlwifi 0000:03:00.0: CONFIG_IWLWIFI_P2P disabled [ 10.362974] iwlwifi 0000:03:00.0: Detected Intel(R) Centrino(R) Wireless-N 2200 BGN, REV=0x104 [ 10.363003] iwlwifi 0000:03:00.0: L1 Disabled; Enabling L0S [ 10.377474] ieee80211 phy0: Selected rate control algorithm 'iwl-agn-rs' [ 1180.920142] iwlwifi 0000:03:00.0: U iwlagn_mac_start enter [ 1180.920152] iwlwifi 0000:03:00.0: I iwl_prep_station Add STA to driver ID 15: ff:ff:ff:ff:ff:ff [ 1180.920158] iwlwifi 0000:03:00.0: I iwl_prep_station Add STA to driver ID 14: ff:ff:ff:ff:ff:ff [ 1180.920163] iwlwifi 0000:03:00.0: U iwl_pcie_prepare_card_hw iwl_trans_prepare_card_hw enter [ 1180.920171] iwlwifi 0000:03:00.0: U iwl_pcie_set_hw_ready hardware ready [ 1180.920173] iwlwifi 0000:03:00.0: U iwl_enable_rfkill_int Enabling rfkill interrupt [ 1180.920180] iwlwifi 0000:03:00.0: U iwl_pcie_apm_init Init card's basic functions [ 1180.920196] iwlwifi 0000:03:00.0: L1 Disabled; Enabling L0S [ 1180.928171] iwlwifi 0000:03:00.0: Radio type=0x2-0x0-0x0 [ 1180.929423] iwlwifi 0000:03:00.0: U iwl_enable_interrupts Enabling interrupts [ 1180.929431] iwlwifi 0000:03:00.0: U iwl_pcie_load_section [0] uCode section being loaded...
