Description of problem: When trying to connect to a an 802.11n network on channel 157 (5785 MHz), I get a kernel panic and am unable to connect. But if I use any other channel, I am able to connect to the network. Version-Release number of selected component (if applicable): Asus USB-N53 wireless adapter Fedora 16 system with all updates applied Fedora linux kernel 3.3.1-3 How reproducible: Everytime Steps to Reproduce: 1. Change channel of my wi-fi network on my access point to 157 (5785 MHz) 2. Try to connect to my network Actual results: Kernel panics and I'm unable to connect Expected results: I should be able to connect to a network on channel 157, just like I can with any other channel.

re-assigned to the kernel
Does the problem can be reproduced with recent kernel ?
First of all this is not "kernel panic" but WARNING, perhaps ABRT call this "kernel panic or kernel crash", but in this case we do not have this kind of problem. Channel 157 is prohibited in Europe, perhaps you are using device dedicated to Europe market. What shows "iw phy" ?
@Nicolas, the problem is still reproducible in Fedora 17 with the 3.3.7-1.fc17.x86_64 kernel. @ Stanislaw, "iw phy" shows the following: [vinu@vinu ~]$ iw phy Wiphy phy0 Band 1: Capabilities: 0x2f2 HT20/HT40 Static SM Power Save RX Greenfield RX HT20 SGI RX HT40 SGI TX STBC RX STBC 2-streams Max AMSDU length: 3839 bytes No DSSS/CCK HT40 Maximum RX AMPDU length 65535 bytes (exponent: 0x003) Minimum RX AMPDU time spacing: 2 usec (0x04) HT RX MCS rate indexes supported: 0-15, 32 TX unequal modulation not supported HT TX Max spatial streams: 2 HT TX MCS rate indexes supported may differ Frequencies: * 2412 MHz [1] (20.0 dBm) * 2417 MHz [2] (20.0 dBm) * 2422 MHz [3] (20.0 dBm) * 2427 MHz [4] (20.0 dBm) * 2432 MHz [5] (20.0 dBm) * 2437 MHz [6] (20.0 dBm) * 2442 MHz [7] (20.0 dBm) * 2447 MHz [8] (20.0 dBm) * 2452 MHz [9] (20.0 dBm) * 2457 MHz [10] (20.0 dBm) * 2462 MHz [11] (20.0 dBm) * 2467 MHz [12] (20.0 dBm) * 2472 MHz [13] (20.0 dBm) * 2484 MHz [14] (disabled) Bitrates (non-HT): * 1.0 Mbps * 2.0 Mbps (short preamble supported) * 5.5 Mbps (short preamble supported) * 11.0 Mbps (short preamble supported) * 6.0 Mbps * 9.0 Mbps * 12.0 Mbps * 18.0 Mbps * 24.0 Mbps * 36.0 Mbps * 48.0 Mbps * 54.0 Mbps Band 2: Capabilities: 0x2f2 HT20/HT40 Static SM Power Save RX Greenfield RX HT20 SGI RX HT40 SGI TX STBC RX STBC 2-streams Max AMSDU length: 3839 bytes No DSSS/CCK HT40 Maximum RX AMPDU length 65535 bytes (exponent: 0x003) Minimum RX AMPDU time spacing: 2 usec (0x04) HT RX MCS rate indexes supported: 0-15, 32 TX unequal modulation not supported HT TX Max spatial streams: 2 HT TX MCS rate indexes supported may differ Frequencies: * 5180 MHz [36] (20.0 dBm) * 5190 MHz [38] (20.0 dBm) * 5200 MHz [40] (20.0 dBm) * 5220 MHz [44] (20.0 dBm) * 5230 MHz [46] (20.0 dBm) * 5240 MHz [48] (20.0 dBm) * 5260 MHz [52] (20.0 dBm) (radar detection) * 5270 MHz [54] (20.0 dBm) (radar detection) * 5280 MHz [56] (20.0 dBm) (radar detection) * 5300 MHz [60] (20.0 dBm) (radar detection) * 5310 MHz [62] (20.0 dBm) (radar detection) * 5320 MHz [64] (20.0 dBm) (radar detection) * 5500 MHz [100] (disabled) * 5510 MHz [102] (disabled) * 5520 MHz [104] (disabled) * 5540 MHz [108] (disabled) * 5550 MHz [110] (disabled) * 5560 MHz [112] (disabled) * 5580 MHz [116] (disabled) * 5590 MHz [118] (disabled) * 5600 MHz [120] (disabled) * 5620 MHz [124] (disabled) * 5630 MHz [126] (disabled) * 5640 MHz [128] (disabled) * 5660 MHz [132] (disabled) * 5670 MHz [134] (disabled) * 5680 MHz [136] (disabled) * 5700 MHz [140] (disabled) * 5745 MHz [149] (20.0 dBm) * 5755 MHz [151] (20.0 dBm) * 5765 MHz [153] (20.0 dBm) * 5785 MHz [157] (20.0 dBm) * 5795 MHz [159] (20.0 dBm) * 5805 MHz [161] (20.0 dBm) * 5825 MHz [165] (20.0 dBm) * 5835 MHz [167] (disabled) * 5845 MHz [169] (disabled) * 5855 MHz [171] (disabled) * 5865 MHz [173] (disabled) Bitrates (non-HT): * 6.0 Mbps * 9.0 Mbps * 12.0 Mbps * 18.0 Mbps * 24.0 Mbps * 36.0 Mbps * 48.0 Mbps * 54.0 Mbps max #

For channel 157, center HT40+ channel is 159 and center HT40- channel is 155. We do not have 155 defined in our tables, i.e. we can not make calibration for it. I don't know if this is actual a bug. I looked at the tables on rt2x00 driver and vendor driver, both looks the same - there is no 155 channel definition. Gertjan, Ivo, any idea if we should support this channel ? Or if calibration on 157 should work ?
