Hi, I am trialling FreeBSD10-BETA2 in an attempt to find bugs etc. I am having a problem with my Atheros 9285 wireless driver which I think might have been around for a while (not new in 10), but I know a lot of work has been done on these drivers in 10. The symptom is I lose my wifi connection after the computer has been running for some time and I get the following errors scrolling on my terminal: *ath0: ath_chan_set: unable to reset channel X (24XX MHz, flags 0xXXX), hal status 14* It looks similar to these 2 bug reports: http://www.freebsd.org/cgi/query-pr.cgi?pr=kern/165543 http://www.freebsd.org/cgi/query-pr.cgi?pr=151198 Has anyone seen this before or have any ideas/suggestions of how I can troubleshoot further? I am using wpa_supplicant and DHCP. If I reboot my wifi works again for a few hours and then stops. # pciconf -lv ath0@pci0:1:0:0: class=0x028000 card=0x10891a3b chip=0x002b168c rev=0x01 hdr=0x00 vendor = 'Atheros Communications Inc.' device = 'AR9285 Wireless Network Adapter (PCI-Express)' class = network # uname -a FreeBSD sparticus.home.local 10.0-BETA2 FreeBSD 10.0-BETA2 #0 r257166: Sat Oct 26 19:23:22 UTC 2013 root@snap.freebsd.org:/usr/obj/usr/src/sys/GENERIC amd64 # cat /etc/rc.conf wpa_supplicant_flags="-sd" wlans_ath0="wlan0" ifconfig_wlan0="WPA DHCP" # cat /etc/wpa_supplicant.conf network={ ssid="SSID" psk="PSK" } # cat /var/log/dmesg.today ath0: ath_chan_set: unable to reset channel 8 (2447 MHz, flags 0x480), hal status 14 ath0: ath_chan_set: unable to reset channel 9 (2452 MHz, flags 0x480), hal status 14 ath0: ath_chan_set: unable to reset channel 10 (2457 MHz, flags 0x480), hal status 14 ath0: ath_chan_set: unable to reset channel 12 (2467 MHz, flags 0x680), hal status 14 ath0: ath_chan_set: unable to reset channel 14 (2484 MHz, flags 0x2a0), hal status 14 ath0: ath_reset: unable to reset hardware; hal status 14 pid 53465 (python), uid 972: exited on signal 6 (core dumped) # cat /var/log/debug.log wpa_supplicant[490]: wlan0: Event SCAN_RESULTS (3) received wpa_supplicant[490]: Received 0 bytes of scan results (0 BSSes) wpa_supplicant[490]: wlan0: BSS: Start scan result update 5935 wpa_supplicant[490]: BSS: last_scan_res_used=0/32 last_scan_full=0 wpa_supplicant[490]: wlan0: New scan results available wpa_supplicant[490]: WPS: AP[0] 30:85:a9:e7:e4:10 type=0 tries=0 last_attempt=-1 sec ago blacklist=2 wpa_supplicant[490]: WPS: AP[1] 00:26:44:9a:d5:21 type=0 tries=0 last_attempt=-1 sec ago blacklist=0 wpa_supplicant[490]: WPS: AP[2] a4:b1:e9:9b:de:9e type=0 tries=0 last_attempt=-1 sec ago blacklist=0 wpa_supplicant[490]: wlan0: No suitable network found wpa_supplicant[490]: wlan0: Setting scan request: 5 sec 0 usec wpa_supplicant[490]: wlan0: Starting AP scan for wildcard SSID wpa_supplicant[490]: wpa_driver_bsd_set_wpa: enabled=1 wpa_supplicant[490]: wpa_driver_bsd_set_wpa_internal: wpa=3 privacy=1 Thanks in advance! -Ben
