https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D214264 Bug ID: 214264 Summary: iwn on 11.0 (Centrino Wireless-N 2230) Product: Base System Version: 11.0-RELEASE Hardware: amd64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: wireless Assignee: freebsd-wireless@FreeBSD.org Reporter: neptunium.element@gmail.com CC: freebsd-amd64@FreeBSD.org CC: freebsd-amd64@FreeBSD.org I have Centrino Wireless-N 2230 adapter (Lenovo IdeaPad S400) which worked = well on 10.X. On 11.0-p2 I experienced a lot of problems with it. Sometimes (albeit not always), on boot, I see something like this: --------------------------------------------------------------------------- iwn0: scan timeout iwn0: iwn_read_firmware: ucode rev=3D0x12a80601 wlan0: link state changed to UP iwn0: iwn_intr: fatal firmware error firmware error log: error type =3D "UNKNOWN" (0x00002529) program counter =3D 0x00029DDC source line =3D 0x000000AC error data =3D 0x0000000100000036 branch link =3D 0x00029DBE00029DBE interrupt link =3D 0x0000EC7A00000000 time =3D 7160 driver status: tx ring 0: qid=3D0 cur=3D0 queued=3D0=20=20 tx ring 1: qid=3D1 cur=3D0 queued=3D0=20=20 tx ring 2: qid=3D2 cur=3D0 queued=3D0=20=20 tx ring 3: qid=3D3 cur=3D2 queued=3D0=20=20 tx ring 4: qid=3D4 cur=3D0 queued=3D0=20=20 tx ring 5: qid=3D5 cur=3D0 queued=3D0=20=20 tx ring 6: qid=3D6 cur=3D0 queued=3D0=20=20 tx ring 7: qid=3D7 cur=3D0 queued=3D0=20=20 tx ring 8: qid=3D8 cur=3D0 queued=3D0=20=20 tx ring 9: qid=3D9 cur=3D60 queued=3D0=20=20 tx ring 10: qid=3D10 cur=3D0 queued=3D0=20=20 tx ring 11: qid=3D11 cur=3D0 queued=3D0=20=20 tx ring 12: qid=3D12 cur=3D0 queued=3D0=20=20 tx ring 13: qid=3D13 cur=3D0 queued=3D0=20=20 tx ring 14: qid=3D14 cur=3D0 queued=3D0=20=20 tx ring 15: qid=3D15 cur=3D0 queued=3D0=20=20 tx ring 16: qid=3D16 cur=3D0 queued=3D0=20=20 tx ring 17: qid=3D17 cur=3D0 queued=3D0=20=20 tx ring 18: qid=3D18 cur=3D0 queued=3D0=20=20 tx ring 19: qid=3D19 cur=3D0 queued=3D0=20=20 rx ring: cur=3D42 iwn0: iwn_panicked: controller panicked, iv_state =3D 5; restarting wlan0: link state changed to DOWN iwn0: iwn_read_firmware: ucode rev=3D0x12a80601 wlan0: link state changed to UP wlan0: link state changed to DOWN iwn0: scan timeout iwn0: iwn_read_firmware: ucode rev=3D0x12a80601 wlan0: link state changed to UP --------------------------------------------------------------------------- Despite this, wifi works after it. However, often (albeit not always) after suspend/resume, iwn0 cannot reconnect, with messages like this: --------------------------------------------------------------------------- Nov 1 22:07:07 neptunium kernel: iwn0: iwn_read_firmware: ucode rev=3D0x12= a80601 Nov 1 22:07:07 neptunium wpa_supplicant[39597]: wlan0: CTRL-EVENT-SCAN-FAI= LED ret=3D-1 retry=3D1 Nov 1 22:07:08 neptunium wpa_supplicant[39597]: ioctl[SIOCS80211, op=3D103, val=3D0, arg_len=3D128]: Operation now in progress Nov 1 22:07:08 neptunium wpa_supplicant[39597]: wlan0: CTRL-EVENT-SCAN-FAI= LED ret=3D-1 retry=3D1 Nov 1 22:07:09 neptunium wpa_supplicant[39597]: ioctl[SIOCS80211, op=3D103, val=3D0, arg_len=3D128]: Operation now in progress Nov 1 22:07:09 neptunium wpa_supplicant[39597]: wlan0: CTRL-EVENT-SCAN-FAI= LED ret=3D-1 retry=3D1 Nov 1 22:07:10 neptunium wpa_supplicant[39597]: ioctl[SIOCS80211, op=3D103, val=3D0, arg_len=3D128]: Operation now in progress Nov 1 22:07:10 neptunium wpa_supplicant[39597]: wlan0: CTRL-EVENT-SCAN-FAI= LED ret=3D-1 retry=3D1 --------------------------------------------------------------------------- or like this: --------------------------------------------------------------------------- ifa_maintain_loopback_route: deletion failed for interface lo0: 48 wlan0: Ethernet address: 68:17:29:a1:b7:47 iwn0: iwn_read_firmware: ucode rev=3D0x12a80601 iwn0: iwn_read_firmware: ucode rev=3D0x12a80601 ifa_maintain_loopback_route: deletion failed for interface lo0: 48 ifa_maintain_loopback_route: deletion failed for interface wlan0: 3 wlan0: Ethernet address: 68:17:29:a1:b7:47 iwn0: iwn_read_firmware: ucode rev=3D0x12a80601 iwn0: iwn_read_firmware: ucode rev=3D0x12a80601 --------------------------------------------------------------------------- I'm aware of bug #208758 and bug #213444, which describe problems similar to mine.=20 As for recommendations from bug #208758, I cannot kldload/kldunload if_iwn (it's in the kernel), and device enable iwn0 (after disabling) causes immed= iate reboot. As for recommendations from #213444, I'm currently testing=20 create_args_wlan0=3D"-ht" However, AFAIU, it will not resolve "fatal firmware error". As I said, I have no problems with iwn on 10.X. --=20 You are receiving this mail because: You are the assignee for the bug.=
