Am suffering from the same bug on a Thinkpad T470s with an Intel 8265 wifi chip running Ubuntu 17.10, Linux kernel 4.13.0-37-generic, and iwlwifi 31.560484.0. There are multiple reports like the errors below in kern.log. After a while, the machine completely locks up. Interestingly, the system only seems to lock up when transferring files using Syncthing or Resilio Sync.

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 0000:02:00.0: Microcode SW error detected. Restarting 0x82000000. (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 0000:02:00.0: enabling device (0000 -> 0002) /var/log/syslog.5.gz:Oct 24 15:37:26 fry kernel: [ 7.611790] iwlwifi 0000:02:00.0: 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 0000:02:00.0: 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 0000:02:00.0: loaded firmware version 31.532993.0 op_mode iwlmvm /var/log/syslog.5.gz:Oct 24 15:37:26 fry kernel: [ 7.650972] iwlwifi 0000:02:00.0: Detected Intel(R) Dual Band Wireless AC 8260, REV=0x208 02:00.0 Network controller: Intel Corporation Wireless 8260 (rev 3a) Any help appreciated.
