Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem? Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.14 kernel[0]. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. Once testing of the upstream kernel is complete, please mark this bug as "Confirmed". Thanks in advance.

[Kernel-packages] [Bug 1733194] Re: kernel NULL pointer dereference in iwlmvm iwl_mvm_enable_txq
I upgraded from 16.04, where I was not having this issue. I think that was running 4.10? I tested with the upstream kernel, and the problem persists.

The txq assignment is: struct iwl_txq *txq = trans_pcie->txq[txq_id]; Bottom line, txq is NULL... Note that we tried (and failed) to open AMPDU a bit before the crash and this is clearly not a classic scenario. I really don't see how trans_pcie->txq[txq_id] could be NULL... If only we knew what was the value of txq_id... Can you load iwlwifi with debug=0x8000 ?

I suffer from this bug too, with this card in access point mode: 02:00.0 Network controller [0280]: Intel Corporation Wireless 7260 [8086:08b1] (rev 73) Subsystem: Intel Corporation Dual Band Wireless-AC 7260 [8086:4070] And kernel 4.15.0-33-generic on Ubuntu 16.04 Xenial, though I encountered it with previous versions too, and I think with 4.4 kernels too. It seems to happen when the load on the network is high. But luckily, according to https://www.spinics.net/lists/linux- wireless/msg169581.html it seems to be fixed in Intel by https://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/backport- iwlwifi.git/commit/?id=b8e2a319df8cc60626ab7dcabbbab64ff56be41e in their release/core35. I think the resulting bug is probably in iwlwifi.ko (linux-image-extra package) (I don't think it is in iwlwifi.ucode). Is there any way to track which release/coreXX is in a kernel version? -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1733194 Title: kernel NULL pointer dereference in iwlmvm iwl_mvm_enable_txq Status in Linux: Incomplete Status in linux package in Ubuntu: Confirmed Bug description: When in AP mode after some time, get this BUG: Nov 18 23:21:31 bifrost kernel: [18345.860393] BUG: unable to handle kernel NULL pointer dereference at 0070 Nov 18 23:21:31 bifrost kernel: [18345.860552] IP: iwl_trans_pcie_txq_enable+0x62/0x440 [iwlwifi] Nov 18 23:21:31 bifrost kernel: [18345.860644] PGD 0 Nov 18 23:21:31 bifrost kernel: [18345.860646] P4D 0 Nov 18 23:21:31 bifrost kernel: [18345.860682] Nov 18 23:21:31 bifrost kernel: [18345.860747] Oops: 0002 [#1] SMP Nov 18 23:21:31 bifrost kernel: [18345.860800] Modules linked in: nfnetlink_queue nfnetlink_log nfnetlink dummy ufs qnx4 hfsplus hfs minix ntfs msdos jfs xfs ccm xfrm_user xfrm4_tunnel tunnel4 ipcomp xfrm_ipcomp esp4 ah4 af_key xfrm_algo xt_policy xt_multiport ip6table_filter ip6_tables ipt_MASQUERADE nf_nat_masquerade_ipv4 iptable_nat nf_nat_ipv4 nf_nat ipt_REJECT nf_reject_ipv4 xt_tcpudp nf_conntrack_ipv4 nf_defrag_ipv4 xt_conntrack nf_conntrack iptable_filter nls_iso8859_1 cmdlinepart intel_spi_platform intel_spi spi_nor mtd arc4 intel_rapl intel_soc_dts_thermal intel_soc_dts_iosf intel_powerclamp coretemp kvm_intel bridge kvm stp llc iwlmvm irqbypass punit_atom_debug mac80211 intel_cstate snd_hda_codec_hdmi iwlwifi snd_hda_codec_realtek snd_hda_codec_generic cfg80211 btusb snd_hda_intel lpc_ich btrtl snd_hda_codec snd_intel_sst_acpi Nov 18 23:21:31 bifrost kernel: [18345.861897] mei_txe snd_hda_core mei snd_hwdep shpchp snd_intel_sst_core snd_soc_sst_atom_hifi2_platform hci_uart snd_soc_sst_match snd_soc_core btbcm serdev snd_compress btqca ac97_bus btintel snd_pcm_dmaengine snd_pcm dw_dmac dw_dmac_core snd_timer bluetooth snd soundcore mac_hid intel_int0002_vgpio ecdh_generic spi_pxa2xx_platform rfkill_gpio pwm_lpss_platform pwm_lpss 8250_dw ib_iser rdma_cm iw_cm ib_cm ib_core iscsi_tcp libiscsi_tcp libiscsi scsi_transport_iscsi ip_tables x_tables autofs4 btrfs raid10 raid456 async_raid6_recov async_memcpy async_pq async_xor async_tx xor raid6_pq libcrc32c raid1 raid0 multipath linear i915 drm_kms_helper crct10dif_pclmul igb syscopyarea sysfillrect crc32_pclmul sysimgblt fb_sys_fops dca ghash_clmulni_intel i2c_algo_bit cryptd ahci ptp drm pps_core libahci video Nov 18 23:21:31 bifrost kernel: [18345.862995] i2c_hid hid sdhci_acpi sdhci Nov 18 23:21:31 bifrost kernel: [18345.863068] CPU: 1 PID: 1202 Comm: kworker/1:2 Tainted: GW 4.13.0-16-generic #19-Ubuntu Nov 18 23:21:31 bifrost kernel: [18345.863203] Hardware name: NF541 NF541/NF541, BIOS BAR1NA02 02/25/2016 Nov 18 23:21:31 bifrost kernel: [18345.863326] Workqueue: events iwl_mvm_add_new_dqa_stream_wk [iwlmvm] Nov 18 23:21:31 bifrost kernel: [18345.863428] task: 96862c1c5800 task.stack: a98a817c Nov 18 23:21:31 bifrost kernel: [18345.863539] RIP: 0010:iwl_trans_pcie_txq_enable+0x62/0x440 [iwlwifi] Nov 18 23:21:31 bifrost kernel: [18345.863635] RSP: 0018:a98a817c3be0 EFLAGS: 00010246 Nov 18 23:21:31 bifrost kernel: [18345.863718] RAX: 09c4 RBX: 001f RCX: Nov 18 23:21:31 bifrost kernel: [18345.863824] RDX: RSI: 001f RDI: 2710 Nov 18 23:21:31 bifrost kernel: [18345.863932] RBP: a98a817c3c30 R08: 2710 R09: 0001 Nov 18 23:21:31 bifrost kernel: [18345.864039] R10: R11: 9686344ce010 R12: Nov 18 23:21:31 bifrost kernel: [18345.864145] R13: 96862c9d0018 R14: R15: Nov 18 23:21:31 bifrost kernel: [18345.864253] FS: () GS:96863fc8() knlGS: Nov 18 23:21:31 bifrost kernel: [18345.864373] CS: 0010 DS: ES: CR0: 80050033
