[Kernel-packages] [Bug 1728651] Re: System hangs after iwlwifi firmware crash
Okay, so, I remembered disabling CStates in BIOS as well as the other Intel speed throttling settings. After re-enabling them, I've been streaming data for quite a while, and haven't had the iwlwifi driver crash. So, "workaround" I guess?? -- 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.

[Kernel-packages] [Bug 1728651] Re: System hangs after iwlwifi firmware crash
Rather old thread, but definitely experiencing a similar problem with the system completely freezing for about 10-15 seconds. Syslog contains the same core dump as posted above (i've pasted mine below ...) It seems to happen during heavy streaming -- for me that's YouTube at the moment. Watching videos' the crash happened numerous times at a regular interval of one minute then a four minute interval and then back to numerous at one minute interval again ... (also pasted below), this seems unusual in its regularity which is why I include it. However switching to an online multiplayer game, during the course of half an hour the crash never occurred, or wasn't logged and then shutting the game and restarting a new YT video, the crash occurred in less than a minute of play (also pasted). One last note, the system didn't freeze during the second crash (@01:51) however did stutter/hang during a subsequent crash at 01:52.

I'm now on 4.16.3 kernel, and while I haven't encountered freeze since moving to 4.15.13+, the WiFi connection becomes slow/unstable after few minutes. I'm not sure this is connected to the same part of code, or my HW meanwhile degraded a bit (did the 4.4 kernel work without a hitch? I may try to boot it for few days to see if it's HW issue, or still regression in kernel and wifi card driver). At this moment this is just a disclaimer to my post above, to make people not expect everything works perfectly after update of kernel, YMMV. For me it at least doesn't freeze any more. -- 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 did switch to mainline kernel 4.15.13 about 10 days back, and so far no single freeze happened. I did use this web page for instructions/etc: https://wiki.ubuntu.com/Kernel/MainlineBuilds I'm on KDE Neon distro, which is basically Ubuntu 16.04 LTS (with latests KDE packages on top of it). This was very annoying period of time (full 3 months?) on the 4.13 kernel with freezing at least 2-3 times per week, I wonder if there's not large enough portion of users affected to check if the update of kernel for ordinary users can be accelerated? -- 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.

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.

[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!).

[Kernel-packages] [Bug 1728651] Re: System hangs after iwlwifi firmware crash
Status changed to 'Confirmed' because the bug affects multiple users. ** Changed in: linux-firmware (Ubuntu) Status: New => Confirmed -- 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.
