[Kernel-packages] [Bug 1728651] Re: System hangs after iwlwifi firmware crash
Based on skimming https://bugzilla.kernel.org/show_bug.cgi?id=195299 I think this might be fixed upstream but didn't make it to kernel 4.13. When will Ubuntu move to 4.14? :) For now I am trying an older microcode (27.541033.0) but am not optimistic.. ** Bug watch added: Linux Kernel Bug Tracker #195299 https://bugzilla.kernel.org/show_bug.cgi?id=195299 -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-firmware in Ubuntu. https://bugs.launchpad.net/bugs/1728651 Title: System hangs after iwlwifi firmware crash Status in linux-firmware package in Ubuntu: Confirmed Bug description: Since upgrading to Kubuntu 17.10 my HP EliteBook 820 G3 hangs at unpredictable times. I have experienced probably 20 hangs. Once the system is hung no mouse movement, NumLock toggle, VT switch, Ctrl+Alt+Del, SysRq keys, SSH attempts have any effect whatsoever. Any audio playing is stuck looping in the hardware buffer. The system is really stuck. Only the keyboard backlight is still responsive. The only correlation I have noticed is that the system only hangs if WiFi is enabled. This morning I experienced two hangs in ten minutes necessitating reboots. Having disabled WiFi the system has been stable since ~1100 (~5 hours). Often, I see a iwlwifi hardware reset in the logs before the system dies: /var/log/syslog:Oct 30 11:49:30 fry kernel: [ 6529.550751] iwlwifi :02:00.0: Microcode SW error detected. Restarting 0x8200. (apport has hopefully uploaded the full log, please lmk if not). Sometimes the message doesn't make it into the logs, and ext4 truncates the file at the next mount. There seems to be no correlation with any messages immediately before the wifi chip dies. It doesn't seem to matter whether I'm at home or at work. I have wired ethernet at work simultaneously with wifi, but the wifi provides IPv6 so I would imagine most traffic uses wifi, so it's hard to say whether there's any effect of the traffic load on the probability of failure. Here is a sample of the firmware load: /var/log/syslog.5.gz:Oct 24 15:37:26 fry kernel: [7.604743] iwlwifi :02:00.0: enabling device ( -> 0002) /var/log/syslog.5.gz:Oct 24 15:37:26 fry kernel: [7.611790] iwlwifi :02:00.0: Direct firmware load for iwlwifi-8000C-33.ucode failed with error -2 /var/log/syslog.5.gz:Oct 24 15:37:26 fry kernel: [7.611930] iwlwifi :02:00.0: Direct firmware load for iwlwifi-8000C-32.ucode failed with error -2 /var/log/syslog.5.gz:Oct 24 15:37:26 fry kernel: [7.620028] iwlwifi :02:00.0: loaded firmware version 31.532993.0 op_mode iwlmvm /var/log/syslog.5.gz:Oct 24 15:37:26 fry kernel: [7.650972] iwlwifi :02:00.0: Detected Intel(R) Dual Band Wireless AC 8260, REV=0x208 02:00.0 Network controller: Intel Corporation Wireless 8260 (rev 3a) Any help appreciated.

[Kernel-packages] [Bug 1728651] Re: System hangs after iwlwifi firmware crash
I believe I also have this bug on a HP Envy 13-ab002na. It is a vanilla 17.10 install. As with @bwduncan the laptop becomes completely unresponsive to any inputs and needs hard power off. The last thing in /var/log/kern.log is iwlwifi Microcode SW error detected. It has happened 3 times in the last 30 min. It had previously been less frequent and mostly only when the machine was sleeping. If I disable WiFi and tether to my phone (via USB) I have not yet experienced such a lockup. I installed 17.10 from new with this laptop so cannot say whether it is 17.10 specific (previously had a ThinkPad; seems I had a narrow escape with the BIOS write bit!).
