Sender: linux-wireless-owner@vger.kernel.org List-ID: Howdy, First I tried ilw@linux.intel.com which is now dead Then linuxwifi@intel.com, but no reply. So I'm trying here next. Any ideas? Sadly before that I was on 4.4 due to bugs in the NVME ACPI suspend support that only got fixed in 4.11, so it's a big jump, my apologies for that. That said, I've used this wireless driver for 1.5 years with that firmware without issues before that (kernel 4.4). When it works, it loads with iwlwifi 0000:04:00.0: Falling back to user helper iwlwifi 0000:04:00.0: loaded firmware version 19.277230.0 op_mode iwlmvm iwlwifi 0000:04:00.0: Detected Intel(R) Dual Band Wireless AC 8260, REV=0x208 iwlwifi 0000:04:00.0: L1 Enabled - LTR Enabled iwlwifi 0000:04:00.0: L1 Enabled - LTR Enabled 3 different ways it's failing now: 1) CPU: 3 PID: 9349 at drivers/net/wireless/intel/iwlwifi/pcie/trans.c:1913 iwl_trans_pcie_grab_nic_access+0xcc/0xe1 [iwlwifi] Timeout waiting for hardware access (CSR_GP_CNTRL 0xffffffff) 2) iwlwifi 0000:04:00.0: loaded firmware version 19.277230.0 op_mode iwlmvm iwlwifi 0000:04:00.0: Detected Intel(R) Dual Band Wireless AC 8260, REV=0xFFFC iwlwifi 0000:04:00.0: L1 Enabled - LTR Enabled iwlwifi 0000:04:00.0: L1 Enabled - LTR Enabled iwlwifi 0000:04:00.0: Could not load the [0] uCode section iwlwifi 0000:04:00.0: Failed to start INIT ucode: -5 iwlwifi 0000:04:00.0: Failed to run INIT ucode: -5 <<<< this 3) iwlwifi 0000:04:00.0: Refused to change power state, currently in D3 Long details below: I noted that https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi says I should use iwlwifi-8000-ucode-16.242414.0.tgz which only ships iwlwifi-8000C-16.ucode while I have iwlwifi-8000C-19.ucode Either way, I just had to reboot my system as the only way for the driver to work again. Once it's loaded, it works, but it's not ok that I have to reboot to get it working again after a suspend/resume module load/unload. Is it a known problem, and is there a fix? Before the reboot, trying to load the module, gave this: Intel(R) Wireless WiFi driver for Linux Copyright(c) 2003- 2015 Intel Corporation ------------[ cut here ]------------ WARNING: CPU: 3 PID: 9349 at drivers/net/wireless/intel/iwlwifi/pcie/trans.c:1913 iwl_trans_pcie_grab_nic_access+0xcc/0xe1 [iwlwifi] Timeout waiting for hardware access (CSR_GP_CNTRL 0xffffffff) Modules linked in: iwlwifi(+) cfg80211 hfs ntfs msdos jfs reiserfs e1000e msr cmac rpcsec_gss_krb5 nfsv4 dns_resolver ccm ipt_MASQUERADE nf_nat_masquerade_ipv4 ipt_REJECT nf_reject_ipv4 xt_tcpudp xt_conntrack nf_log_ipv4 nf_log_common xt_LOG iptable_nat nf_conntrack_ipv4 nf_defrag_ipv4 nf_nat_ipv4 nf_nat nf_conntrack iptable_mangle rfcomm ebtable_filter ebtables ip6table_filter ip6_tables iptable_filter ip_tables x_tables bnep pci_stub vboxpci(OE) vboxnetadp(OE) vboxnetflt(OE) vboxdrv(OE) autofs4 binfmt_misc uinput nfsd auth_rpcgss nfs_acl nfs lockd grace fscache sunrpc nls_utf8 nls_cp437 vfat fat configs input_polldev loop firewire_sbp2 firewire_core crc_itu_t cuse ecryptfs ppdev parport_pc lp parport uvcvideo hid_generic videobuf2_vmalloc videobuf2_memops videobuf2_v4l2 videobuf2_core  btusb videodev btrtl btbcm btintel media bluetooth usbhid hid joydev arc4 coretemp snd_hda_codec_realtek snd_hda_codec_generic x86_pkg_temp_thermal intel_powerclamp kvm_intel kvm snd_hda_intel irqbypass snd_hda_codec crct10dif_pclmul crc32_pclmul snd_hda_core iTCO_wdt snd_hwdep rtsx_pci_ms snd_pcm ghash_clmulni_intel efi_pstore mei_wdt memstick rtsx_pci_sdmmc iTCO_vendor_support intel_cstate snd_seq nouveau snd_seq_device mxm_wmi intel_rapl_perf thinkpad_acpi efivars xhci_pci snd_timer psmouse pcspkr ttm nvram xhci_hcd nvidiafb i2c_i801 rtsx_pci vgastate snd sg usbcore fb_ddc soundcore mei_me intel_pch_thermal rfkill hwmon ac battery tpm_crb tpm_tis wmi tpm_tis_core tpm sata_sil24 r8169 mii fuse fan raid456 multipath mmc_block mmc_core dm_snapshot dm_bufio dm_mirror dm_region_hash dm_log  dm_crypt dm_mod async_raid6_recov async_pq async_xor async_memcpy async_tx blowfish_x86_64 blowfish_common crc32c_intel bcache aesni_intel aes_x86_64 crypto_simd ptp input_leds cryptd i915 glue_helper serio_raw pps_core shpchp thermal evdev [last unloaded: cfg80211] CPU: 3 PID: 9349 Comm: modprobe Tainted: G W OE 4.11.1-amd64-preempt-sysrq-20170406 #4 Hardware name: LENOVO 20ERCTO1WW/20ERCTO1WW, BIOS N1DET41W (1.15 ) 12/31/2015 Call Trace:  dump_stack+0x61/0x7d  __warn+0xc2/0xdd  warn_slowpath_fmt+0x5a/0x76  ? iwl_read32+0x1f/0x7f [iwlwifi]  iwl_trans_pcie_grab_nic_access+0xcc/0xe1 [iwlwifi]  iwl_trans_pcie_alloc+0x2fb/0x7d4 [iwlwifi]  iwl_pci_probe+0x30/0x301 [iwlwifi]  ? _raw_spin_unlock_irqrestore+0x14/0x24  ? __pm_runtime_resume+0x4d/0x58  local_pci_probe+0x3d/0x80  pci_device_probe+0xf9/0x13c  driver_probe_device+0x19d/0x3f2  __driver_attach+0x80/0xdb  ? driver_probe_device+0x3f2/0x3f2  bus_for_each_dev+0x69/0xa7  driver_attach+0x1e/0x20  bus_add_driver+0xfd/0x239  driver_register+0x88/0xbf  ? 0xffffffffc0ade000  __pci_register_driver+0x4c/0x4e  iwl_pci_register_driver+0x24/0x3b [iwlwifi]  ? 0xffffffffc0ade000  iwl_drv_init+0x65/0x67 [iwlwifi]  do_one_initcall+0x9f/0x160  ? slab_pre_alloc_hook+0x1a/0x44  ? slab_post_alloc_hook.isra.47+0xe/0x1d  ? kmem_cache_alloc_trace+0xec/0xfc  do_init_module+0x5f/0x1f7  load_module+0x1e6e/0x2595  ? strstarts+0x28/0x28  ? vfs_read+0xb5/0xdc  SYSC_finit_module+0xa2/0xe6  ?
