I thought this was what EXPERT was used for: menuconfig EXPERT bool "Configure standard kernel features (expert users)" # Unhide debug options, to make the on-by-default options visible select DEBUG_KERNEL help This option allows certain base kernel options and settings to be disabled or tweaked. This is for specialized environments which can tolerate a "non-standard" kernel. Only use this if you really know what you are doing. But it seems that it's widely used even by people/distros who don't know what they are doing. :( Would it be okay if we just add a printk(KERN_ERR, ...)? > > We discussed this before and that's why this option now depends on > > EXPERT. > > Heh, we did?

And subtle bugs like this are even worse as the user will not realise that it's because of a new Kconfig option. So I guess you can't automatically detect it the platform supports RTPM, right? Maybe there should be a module parameter which has to be set to enable this? And at least a big fat warning to the user that RTPM is enabled, bugs are likely and the user has to know what she's doing. > We discussed this before and that's why this option now depends on > EXPERT.

The problem is that to get this to work, some changes need to be made in the platform side. In this case, the rootport is not configured properly so it won't work. We discussed this before and that's why this option now depends on EXPERT. -- Luca.

The problem seems to be that the rootport is not leaving D3 for some reason when the driver is loaded again. Do you have CONFIG_IWLWIFI_PCIE_RTPM enabled in your .config?

But unfortunately I made a mistake in the patch[1] when I removed support for those firmwares and I used 17, which is the lowest version for 7260 devices. I have just sent out a patch[2] with a fix for that. You can probably solve your problem by getting the latest firmware we have released, which is version 27. You can get it from the linux- firmware.git repository[3]. Please try that and let us know how it goes.

After upgrading to 4.11.1, wifi driver refuses to load after being unloaded once.
Howdy, First I tried i...@linux.intel.com which is now dead Then linuxw...@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 :04:00.0: Falling back to user helper iwlwifi :04:00.0: loaded firmware version 19.277230.0 op_mode iwlmvm iwlwifi :04:00.0: Detected Intel(R) Dual Band Wireless AC 8260, REV=0x208 iwlwifi :04:00.0: L1 Enabled - LTR Enabled iwlwifi :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 0x) 2) iwlwifi :04:00.0: loaded firmware version 19.277230.0 op_mode iwlmvm iwlwifi :04:00.0: Detected Intel(R) Dual Band Wireless AC 8260, REV=0xFFFC iwlwifi :04:00.0: L1 Enabled - LTR Enabled iwlwifi :04:00.0: L1 Enabled - LTR Enabled iwlwifi :04:00.0: Could not load the [0] uCode section iwlwifi :04:00.0: Failed to start INIT ucode: -5 iwlwifi :04:00.0: Failed to run INIT ucode: -5 this 3) iwlwifi :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: [0mIntel(R) Wireless WiFi driver for Linux [0mCopyright(c) 2003- 2015 Intel Corporation [0m[1m[ cut here ][0m [0m[33mWARNING[0m[1m: CPU: 3 PID: 9349 at drivers/net/wireless/intel/iwlwifi/pcie/trans.c:1913 iwl_trans_pcie_grab_nic_access+0xcc/0xe1 [iwlwifi][0m [0m[1mTimeout waiting for hardware access (CSR_GP_CNTRL 0x)[0m [0m[33mModules linked in[0m[1m: 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[0m [0m[1m 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[0m [0m[33m 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[0m[1m: cfg80211][0m [0m[33mCPU[0m[1m: 3 PID: 9349 Comm: modprobe Tainted: GW OE 4.11.1-amd64-preempt-sysrq-20170406 #4[0m [0m[33mHardware name[0m[1m: LENOVO 20ERCTO1WW/20ERCTO1WW, BIOS N1DET41W (1.15 ) 12/31/2015[0m [0m[1mCall Trace:[0m [0m[1m dump_stack+0x61/0x7d[0m [0m[1m __warn+0xc2/0xdd[0m [0m[1m warn_slowpath_fmt+0x5a/0x76[0m [0m[1m ? iwl_read32+0x1f/0x7f [iwlwifi][0m [0m[1m iwl_trans_pcie_grab_nic_access+0xcc/0xe1 [iwlwifi][0m [0m[1m iwl_trans_pcie_alloc+0x2fb/0x7d4 [iwlwifi][0m [0m[1m iwl_pci_probe+0x30/0x301 [iwlwifi][0m [0m[1m ? _raw_spin_unlock_irqrestore+0x14/0x24[0m [0m[1m ? __pm_runtime_resume+0x4d/0x58[0m [0m[1m local_pci_probe+
