Hi, I am having issues in operating mesh mode on QCA9888 chipset. When I bring up the mesh interface, my links are not established. I have tried iw and wpa_supplicant tools for creating mesh, but all end up at the same issue. dmesg command output showed there was panic on kernel as shown below: Aug 23 23:41:41 mydev kernel: [ 1384.897186] ath10k_pci 0000:05:00.0: unsupported HTC service id: 1536 Aug 23 23:41:41 mydev kernel: [ 1384.918285] ath10k_pci 0000:05:00.0: pdev param 0 not supported by firmware Aug 23 23:41:41 mydev kernel: [ 1384.944568] IPv6: ADDRCONF(NETDEV_CHANGE): mesh2: link becomes ready Aug 23 23:41:46 mydev kernel: [ 1389.253229] ath10k_pci 0000:04:00.0: unsupported HTC service id: 1536 Aug 23 23:41:46 mydev kernel: [ 1389.273405] ath10k_pci 0000:04:00.0: pdev param 0 not supported by firmware Aug 23 23:41:46 mydev kernel: [ 1389.298658] IPv6: ADDRCONF(NETDEV_CHANGE): mesh1: link becomes ready Aug 23 23:41:47 mydev kernel: [ 1390.129916] ------------[ cut here ]------------ Aug 23 23:41:47 mydev kernel: [ 1390.129931] WARNING: CPU: 7 PID: 0 at net/core/flow_dissector.c:958 __skb_flow_dissect+0x3ba/0x1590 Aug 23 23:41:47 mydev kernel: [ 1390.129932] Modules linked in: xt_CHECKSUM xt_MASQUERADE xt_conntrack ipt_REJECT nf_reject_ipv4 xt_tcpudp ip6table_mangle ip6table_nat iptable_mangle iptable_nat nf_tables nfnetlink ip6table_filter bridge ip6_tables stp llc iptable_filter bpfilter snd_hda_codec_hdmi snd_hda_codec_realtek snd_hda_codec_generic intel_rapl_msr intel_rapl_common x86_pkg_temp_thermal intel_powerclamp coretemp kvm_intel kvm snd_sof_pci snd_sof_intel_hda_common snd_soc_hdac_hda snd_sof_intel_hda snd_sof_intel_byt snd_sof_intel_ipc snd_sof snd_sof_xtensa_dsp snd_hda_ext_core snd_soc_acpi_intel_match snd_soc_acpi ledtrig_audio snd_soc_core mei_hdcp snd_compress ac97_bus snd_pcm_dmaengine snd_hda_intel snd_intel_dspcfg snd_hda_codec snd_hda_core snd_hwdep nls_iso8859_1 snd_pcm crct10dif_pclmul ghash_clmulni_intel ath10k_pci ath10k_core snd_seq_midi snd_seq_midi_event ath snd_rawmidi mac80211 snd_seq aesni_intel dell_wmi crypto_simd dell_smbios snd_seq_device cryptd dcdbas glue_helper snd_timer joydev intel_cstate Aug 23 23:41:47 mydev kernel: [ 1390.129986] dell_wmi_aio i915 dell_wmi_descriptor input_leds intel_rapl_perf sparse_keymap cfg80211 intel_wmi_thunderbolt wmi_bmof snd openvswitch nsh drm_kms_helper soundcore nf_conncount libarc4 i2c_algo_bit nf_nat mei_me fb_sys_fops syscopyarea nf_conntrack mei sysfillrect sysimgblt intel_pch_thermal nf_defrag_ipv6 ie31200_edac nf_defrag_ipv4 libcrc32c mac_hid acpi_pad sch_fq_codel parport_pc ppdev lp parport drm ip_tables x_tables autofs4 hid_logitech_hidpp hid_logitech_dj hid_generic usbhid hid crc32_pclmul e1000e nvme intel_lpss_pci ahci i2c_i801 intel_lpss nvme_core idma64 libahci virt_dma wmi pinctrl_cannonlake video pinctrl_intel Aug 23 23:41:47 mydev kernel: [ 1390.130034] CPU: 7 PID: 0 Comm: swapper/7 Not tainted 5.4.0-42-generic #46-Ubuntu Aug 23 23:41:47 mydev kernel: [ 1390.130036] Hardware name: Dell Inc.
