When I boot on kernel 3.1, my Wifi card doesn't run. When I "modprobe iwlagn", I have this error : iwlagn: probe of 0000:0c:00.0 failed with error -1 Reproducible: Always Steps to Reproduce: 1. modprobe iwlagn Actual Results: iwlagn: probe of 0000:0c:00.0 failed with error -1 My card : 0c:00.0 Network controller: Intel Corporation Centrino Ultimate-N 6300 (rev 35) # grep IWL .config CONFIG_IWLAGN=m # CONFIG_IWLWIFI_DEBUG is not set # CONFIG_IWLWIFI_DEVICE_TRACING is not set CONFIG_IWLWIFI_DEVICE_SVTOOL=y # CONFIG_IWL_P2P is not set # CONFIG_IWL4965 is not set # CONFIG_IWL3945 is not set
