A) I know you are confuse this bug, because the Atheros is have two interfaces in one device, firstly it had Atheros QCA9565 / AR9565 Wireless Network Adapter and second it had AR3012 Bluetooth 4.0
1. This bug happened on the wireless network, sometime when the wireless handle high traffic like when I do streaming concert that takes about 2 hours. Segmentation fault also happened. 2. About this comment, like what I said on point 1 leaving bluetooth off, segmentation fault still happened when I do streaming. B) At this point segmentation fault also happened, so what that's affect to me? I can't surf the internet network or running the ping command that also unable to do that. Alright, at this time I also found another segmentation fault when I used kernel 4.18-rc [37884.215497] ------------[ cut here ]------------ [37884.215502] wlp2s0: invalid CW_min/CW_max: 30489/7632 [37884.215579] WARNING: CPU: 2 PID: 18792 at /home/kernel/COD/linux/net/mac80211/driver-ops.c:175 drv_conf_tx+0x1a5/0x1b0 [mac80211] [37884.215581] Modules linked in: hid_generic rfcomm pci_stub vboxpci(OE) vboxnetadp(OE) vboxnetflt(OE) vboxdrv(OE) ccm ec_sys cmac uhid hid bnep binfmt_misc nls_iso8859_1 intel_rapl x86_pkg_temp_thermal intel_powerclamp coretemp kvm_intel kvm ath3k irqbypass morus1280_avx2 morus1280_sse2 morus1280_glue morus640_sse2 morus640_glue rtsx_usb_ms aegis256_aesni aegis128l_aesni aegis128_aesni memstick btusb rts5139(OE) crct10dif_pclmul btrtl crc32_pclmul btbcm ghash_clmulni_intel btintel uvcvideo bluetooth videobuf2_vmalloc videobuf2_memops videobuf2_v4l2 videobuf2_common snd_hda_codec_conexant pcbc videodev ecdh_generic media snd_hda_codec_generic snd_hda_codec_hdmi aesni_intel aes_x86_64 crypto_simd snd_hda_intel cryptd snd_hda_codec snd_hda_core snd_hwdep arc4 glue_helper ath9k intel_cstate ath9k_common [37884.215653] snd_pcm ath9k_hw ath snd_seq_midi joydev input_leds intel_rapl_perf mac80211 snd_seq_midi_event serio_raw cfg80211 snd_rawmidi mei_me snd_seq snd_seq_device snd_timer snd ideapad_laptop(OE) mei sparse_keymap lpc_ich soundcore mac_hid sch_fq_codel parport_pc ppdev lp parport ip_tables x_tables rtsx_usb_sdmmc rtsx_usb i915 i2c_algo_bit drm_kms_helper syscopyarea sysfillrect sysimgblt psmouse fb_sys_fops r8169 drm mii ahci libahci video [37884.215709] CPU: 2 PID: 18792 Comm: kworker/u16:1 Tainted: G OE 4.18.0-041800rc1-generic #201806162031 [37884.215711] Hardware name: LENOVO 20369/Lancer 4A2, BIOS 9ACN29WW 10/20/2014 [37884.215743] Workqueue: phy0 ieee80211_iface_work [mac80211] [37884.215769] RIP: 0010:drv_conf_tx+0x1a5/0x1b0 [mac80211] [37884.215770] Code: 41 5d 41 5e 41 5f 5d c3 41 0f b7 4f 04 48 8d b3 28 04 00 00 0f b7 d0 48 c7 c7 00 97 84 c0 c6 05 fe 37 09 00 01 e8 6b d7 0b da <0f> 0b e9 a9 fe ff ff 0f 1f 40 00 0f 1f 44 00 00 55 48 89 e5 41 55 [37884.215834] RSP: 0018:ffffbad4825afc88 EFLAGS: 00010286 [37884.215837] RAX: 0000000000000000 RBX: ffff9de2077b08c0 RCX: 0000000000000006 [37884.215839] RDX: 0000000000000007 RSI: 0000000000000086 RDI: ffff9de20f2964b0 [37884.215841] RBP: ffffbad4825afcb0 R08: 000000000000036a R09: 0000000000000004 [37884.215843] R10: 000000000000ffff R11: 0000000000000001 R12: 00000000ffffffea [37884.215846] R13: ffff9de1fba08760 R14: 0000000000000000 R15: ffffbad4825afce6 [37884.215849] FS: 0000000000000000(0000) GS:ffff9de20f280000(0000) knlGS:0000000000000000 [37884.215851] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [37884.215853] CR2: 00007f81c5ad9080 CR3: 000000018ec0a005 CR4: 00000000001606e0 [37884.215855] Call Trace: [37884.215892] ieee80211_set_wmm_default+0x19c/0x390 [mac80211] [37884.215927] ieee80211_set_disassoc+0x223/0x5d0 [mac80211] [37884.215935] ?
