Hi Sam, do you know if there is anything done about cbb(4)? I have many wireless adapters with ath(4), but only the one based on PCMCIA is making problems on FreeBSD. I cannot boot my notebook with the device inserted into the port, or it will render the system unusable (100% load on cbb(4)). And all I can see is the following: Jul 12 14:58:39 link kernel: ath0: ath_chan_set: unable to reset channel 1 = (2412 Mhz, flags 0x480 hal flags 0xc0), hal status 0 Jul 12 14:58:40 link kernel: ath0: ath_chan_set: unable to reset channel 6 = (2437 Mhz, flags 0x480 hal flags 0xc0), hal status 3233070656 Jul 12 14:58:41 link kernel: ath0: ath_chan_set: unable to reset channel 7 = (2442 Mhz, flags 0x480 hal flags 0xc0), hal status 3233070656 Jul 12 14:58:42 link kernel: ath0: ath_chan_set: unable to reset channel 2 = (2417 Mhz, flags 0x480 hal flags 0xc0), hal status 0 Jul 12 14:58:43 link kernel: ath0: ath_chan_set: unable to reset channel 3 = (2422 Mhz, flags 0x480 hal flags 0xc0), hal status 0 Jul 12 14:58:44 link kernel: ath0: ath_chan_set: unable to reset channel 4 = (2427 Mhz, flags 0x480 hal flags 0xc0), hal status 3233070656 Jul 12 14:58:45 link kernel: ath0: ath_chan_set: unable to reset channel 5 = (2432 Mhz, flags 0x480 hal flags 0xc0), hal status 0 Jul 12 14:58:45 link kernel: ath0: ath_chan_set: unable to reset channel 8 = (2447 Mhz, flags 0x480 hal flags 0xc0), hal status 0 Jul 12 14:58:46 link kernel: ath0: ath_chan_set: unable to reset channel 9 = (2452 Mhz, flags 0x480 hal flags 0xc0), hal status 0 Jul 12 14:58:47 link kernel: ath0: ath_chan_set: unable to reset channel 10= (2457 Mhz, flags 0x480 hal flags 0xc0), hal status 0 Jul 12 14:58:52 link kernel: ath0: device timeout Jul 12 14:58:52 link kernel: ath0: ath_reset: unable to reset hardware; hal= status 3231908395 Jul 12 14:58:58 link kernel: ath0: ath_chan_set: unable to reset channel 1 = (2412 Mhz, flags 0x480 hal flags 0xc0), hal status 3233070656 Jul 12 14:58:59 link kernel: ath0: ath_chan_set: unable to reset channel 6 = (2437 Mhz, flags 0x480 hal flags 0xc0), hal status 0 Jul 12 14:59:00 link kernel: ath0: ath_chan_set: unable to reset channel 7 = (2442 Mhz, flags 0x480 hal flags 0xc0), hal status 0 Jul 12 14:59:01 link kernel: ath0: ath_chan_set: unable to reset channel 2 = (2417 Mhz, flags 0x480 hal flags 0xc0), hal status 0 Jul 12 14:59:01 link kernel: ath0: ath_chan_set: unable to reset channel 3 = (2422 Mhz, flags 0x480 hal flags 0xc0), hal status 3289233408 Jul 12 14:59:02 link kernel: ath0: ath_chan_set: unable to reset channel 4 = (2427 Mhz, flags 0x480 hal flags 0xc0), hal status 0 Jul 12 14:59:03 link kernel: ath0: ath_chan_set: unable to reset channel 5 = (2432 Mhz, flags 0x480 hal flags 0xc0), hal status 0 Jul 12 14:59:04 link kernel: ath0: ath_chan_set: unable to reset channel 8 = (2447 Mhz, flags 0x480 hal flags 0xc0), hal status 0 Jul 12 14:59:05 link kernel: ath0: ath_chan_set: unable to reset channel 9 = (2452 Mhz, flags 0x480 hal flags 0xc0), hal status 0 Jul 12 14:59:06 link kernel: ath0: ath_chan_set: unable to reset channel 10= (2457 Mhz, flags 0x480 hal flags 0xc0), hal status 0 Jul 12 14:59:10 link kernel: ath0: device timeout Jul 12 14:59:10 link kernel: ath0: ath_reset: unable to reset hardware; hal= status 3231908395 Jul 12 14:59:11 link kernel: ath0: ath_chan_set: unable to reset channel 1 = (2412 Mhz, flags 0x480 hal flags 0xc0), hal status 3233070656 Jul 12 14:59:12 link kernel: ath0: ath_chan_set: unable to reset channel 6 = (2437 Mhz, flags 0x480 hal flags 0xc0), hal status 0 Jul 12 14:59:13 link kernel: ath0: ath_chan_set: unable to reset channel 7 = (2442 Mhz, flags 0x480 hal flags 0xc0), hal status 3233070656 Jul 12 14:59:14 link kernel: ath0: ath_chan_set: unable to reset channel 2 = (2417 Mhz, flags 0x480 hal flags 0xc0), hal status 0 Jul 12 14:59:15 link kernel: ath0: ath_chan_set: unable to reset channel 3 = (2422 Mhz, flags 0x480 hal flags 0xc0), hal status 0 Jul 12 14:59:16 link kernel: ath0: unable to reset hardware; hal status 386= 8687084 Jul 12 14:59:16 link kernel: ath0: ath_chan_set: unable to reset channel 4 = (2427 Mhz, flags 0x480 hal flags 0xc0), hal status 0 Jul 12 14:59:17 link kernel: ath0: ath_chan_set: unable to reset channel 11= (2462 Mhz, flags 0x480 hal flags 0xc0), hal status 3828804624 Jul 12 14:59:22 link kernel: ath0: unable to reset hardware; hal status 386= 8539700 Jul 12 14:59:32 link kernel: ath0: unable to reset hardware; hal status 386= 8539700 Jul 12 14:59:42 link kernel: ath0: unable to reset hardware; hal status 386= 8539700 Jul 12 15:00:22 link last message repeated 4 times Jul 12 15:00:32 link kernel: ath0: unable to reset hardware; hal status 386= 8539700 Jul 12 15:00:42 link kernel: ath0: unable to reset hardware; hal status 386= 8539700 Jul 12 15:00:52 link kernel: ath0: unable to reset hardware; hal status 386= 8539700 wpa_supplicant is trying to access the card and switching channels, I suppose. A workaround that I'm using all the time is: 1) boot the notebook without the PCMCIA card 2) after gdm appears, insert the card Also see: http://www.freebsd.org/cgi/query-pr.cgi?pr=3Dkern/120376 In this PR I also described that you can panic the system, while trying to fix the situation by reinserting the card. But I found out, that you can always panic the system when ejecting the card and wpa_supplicant is running. --=20 Gru=C3=9F, Martin Sugioarto | Lehrstuhl Informatik 14 | | TU-Do //// TU Dortmund | | //// Otto-Hahn-Stra=C3=9Fe 14 | | \.\\/// D-44227 Dortmund | | \\\\/ Tel.
