  1. I added armbian stretch/utils repository to my apt sources (I had only stretch/main before). This caused upgrade of my hostapd from Debian to Armbian version, and apparently this fixed the situaton (wlan0 is properly initialized in AP mode and included into br0). However I did not test actual WiFi clients there yes, as this system is remote. Also did not test USB WiFi adapters as I go with onboard WiFi only.
  2. hostapd.conf is very short : logger_syslog=-1 logger_syslog_level=2 interface=wlan0 driver=nl80211 bridge=br0 ssid=xxxxxxxx channel=7 wpa=2 wpa_key_mgmt=WPA-PSK wpa_passphrase=yyyyyyyyyyyy
  3. Having the same problem as rom nl80211: Set mode ifindex 4 iftype 3 (AP) nl80211: Setup AP(wlan0) - device_ap_sme=1 use_monitor=0 nl80211: Subscribe to mgmt frames with AP handle 0x1bd2038 (device SME) nl80211: Register frame type=0xd0 (WLAN_FC_STYPE_ACTION) nl_handle=0x1bd2038 match= nl80211: Register frame command failed (type=208): ret=-22 (Invalid argument) nl80211: Register frame match - hexdump(len=0): [NULL] nl80211: Could not configure driver mode interface wlan0 remains 'down' and is not included into bridge 'br0' linux-image-next-sunxi 5.73 , kernel version 4.19.17-sunxi , hostapd 2:2.4-1+deb9u2 should we add some new options on loading module 'brcmfmac' ?
  4. Same problem have I After upgrade of kernel 4.14 to 4.19, the name of firmware file seems to have been changed, and now it is a bit unclear where to get this file (or would just renaming/hardlinking /lib/firmware/brcm/brcmfmac43362-sdio.bin into brcmfmac43362-sdio.clm_blob be enough ?) My hardware is also Cubietruck as of 2013.
  5. I had similar experience on my Cubietruck A20 (rcu_sched stalls and rejected forks) It happened after my first reboot with kernel 4.14.15-sunxi (after some uptime with kernel 4.13.16) I just run 'sudo cruft' at that time Feb 2 15:58:35 localhost kernel: [102644.225181] INFO: rcu_sched detected stalls on CPUs/tasks: Feb 2 15:58:35 localhost kernel: [102644.225228] 1-...: (1 GPs behind) idle=272/140000000000000/0 softirq=1869227/1869228 fqs=1050 Feb 2 15:58:35 localhost kernel: [102644.225232] (detected by 0, t=2102 jiffies, g=798178, c=798177, q=5594) Feb 2 15:58:35 localhost kernel: [102644.225258] Sending NMI from CPU 0 to CPUs 1: Feb 2 15:59:38 localhost kernel: [102707.275047] INFO: rcu_sched detected stalls on CPUs/tasks: Feb 2 15:59:38 localhost kernel: [102707.275093] 1-...: (1 GPs behind) idle=272/140000000000000/0 softirq=1869227/1869228 fqs=3702 Feb 2 15:59:38 localhost kernel: [102707.275097] (detected by 0, t=8407 jiffies, g=798178, c=798177, q=68757) Feb 2 15:59:38 localhost kernel: [102707.275122] Sending NMI from CPU 0 to CPUs 1: Feb 2 15:59:51 localhost kernel: [102730.056354] cgroup: fork rejected by pids controller in /user.slice/user-1001.slice/session-222.scope Feb 2 16:00:41 localhost kernel: [102770.324854] INFO: rcu_sched detected stalls on CPUs/tasks: Feb 2 16:00:41 localhost kernel: [102770.324890] 1-...: (1 GPs behind) idle=272/140000000000000/0 softirq=1869227/1869228 fqs=6354 Feb 2 16:00:41 localhost kernel: [102770.324894] (detected by 0, t=14712 jiffies, g=798178, c=798177, q=89964) Feb 2 16:00:41 localhost kernel: [102770.324918] Sending NMI from CPU 0 to CPUs 1: Feb 2 16:01:45 localhost kernel: [102833.374711] INFO: rcu_sched detected stalls on CPUs/tasks: Feb 2 16:01:45 localhost kernel: [102833.374751] 1-...: (1 GPs behind) idle=272/140000000000000/0 softirq=1869227/1869228 fqs=9006 Feb 2 16:01:45 localhost kernel: [102833.374756] (detected by 0, t=21017 jiffies, g=798178, c=798177, q=90505) Feb 2 16:01:45 localhost kernel: [102833.374781] Sending NMI from CPU 0 to CPUs 1: Feb 2 16:02:48 localhost kernel: [102896.424568] INFO: rcu_sched detected stalls on CPUs/tasks: Feb 2 16:02:48 localhost kernel: [102896.424608] 1-...: (1 GPs behind) idle=272/140000000000000/0 softirq=1869227/1869228 fqs=11657 Feb 2 16:02:48 localhost kernel: [102896.424612] (detected by 0, t=27322 jiffies, g=798178, c=798177, q=91242) Feb 2 16:02:48 localhost kernel: [102896.424636] Sending NMI from CPU 0 to CPUs 1: Feb 2 16:03:51 localhost kernel: [102959.474426] INFO: rcu_sched detected stalls on CPUs/tasks: Feb 2 16:03:51 localhost kernel: [102959.474465] 1-...: (1 GPs behind) idle=272/140000000000000/0 softirq=1869227/1869228 fqs=14307 Feb 2 16:03:51 localhost kernel: [102959.474469] (detected by 0, t=33627 jiffies, g=798178, c=798177, q=92168) Feb 2 16:03:51 localhost kernel: [102959.474493] Sending NMI from CPU 0 to CPUs 1: Feb 2 16:04:31 localhost kernel: [103009.885942] cgroup: fork rejected by pids controller in /user.slice/user-1001.slice/session-229.scope Then I rebooted the board locally by its power switch, and nothing similar happened after that
