https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=218607 Bug ID: 218607 Summary: rtwn0: r92c_handle_c2h_task: C2H report 15 (len 15) was not handled Product: Base System Version: CURRENT Hardware: arm OS: Any Status: New Severity: Affects Only Me Priority: --- Component: wireless Assignee: freebsd-wireless@FreeBSD.org Reporter: otacilio.neto@bsd.com.br I'm using a beaglebone to stream videos over wifi. For this, I'm testing two wifi adapters: rtwn0: MAC/BB RTL8188CUS, RF 6052 1T1R run0: MAC/BBP RT5390 (rev 0x0502), RF RT5370 (MIMO 1T1R), address e8:4e:06:3c:fd:5d Both adapters works fine at low bit rate (300 Kbps), but when I use a high bi rate, for example 3 Mbps the adapter RTL8188CUS hangs up with the message below: =============================================================================== rtwn0: at uhub2, port 3, addr 4 (disconnected) rtwn0: device timeout Network is down [ota@beaglebone ~/workspace/SOFTWARE_Espelho/Capture]$ rtwn0: r92c_handle_c2h_task: C2H report 15 (len 15) was not handled Apr 12 10:58:06 beaglebone openvpn[759]: write UDP: Network is down (code=50) Apr 12 10:58:10 beaglebone wpa_supplicant[1436]: ioctl[SIOCS80211, op=20, val=0, arg_len=7]: Can't assign requested address rtwn0: ieee80211_crypto_encap returns NULL. rtwn0: ieee80211_crypto_encap returns NULL. Apr 12 10:58:10 beaglebone wpa_supplicant[1436]: ioctl[SIOCS80211, op=103, val=0, arg_len=128]: Device not configured Apr 12 10:58:16 beaglebone last message repeated 6 times Apr 12 10:58:16 beaglebone openvpn[759]: write UDP: Network is down (code=50) Apr 12 10:58:17 beaglebone wpa_supplicant[1436]: ioctl[SIOCS80211, op=103, val=0, arg_len=128]: Device not configured =============================================================================== This occurs only with the RTL8188CUS (rtwn). The adapter RT5390 (run) works fine on both situation and never hangs up. So, the FreeBSD version is: FreeBSD beaglebone 12.0-CURRENT FreeBSD 12.0-CURRENT #1 r316378M: Thu Apr 6 01:08:51 -03 2017 ota@beaglebone:/mnt/obj/mnt/src/sys/BEAGLEBONE arm -- You are receiving this mail because: You are the assignee for the bug.help
