Bug 196109

Created attachment 257059 [details]
Full error text from syslog

I'm on an Intel NUC system with an Intel 8260 Wireless controller.

My config:

> [nathan@nathanb-nuc ~/tmp] uname -a
> Linux nathanb-nuc 4.11.5-1-ARCH #1 SMP PREEMPT Wed Jun 14 16:19:27 CEST 2017
> x86_64 GNU/Linux
> [nathan@nathanb-nuc ~/tmp] lspci | grep -i network
> 03:00.0 Network controller: Intel Corporation Wireless 8260 (rev 3a)
>[nathan@nathanb-nuc ~/tmp] lsmod | grep iwlwifi
> iwlwifi               192512  1 iwlmvm
> cfg80211              520192  3 iwlmvm,iwlwifi,mac80211

I am seeing this in the syslogs a lot:

> Jun 18 16:25:02 nathanb-nuc kernel: iwlwifi 0000:03:00.0: Microcode SW error
> detected.  Restarting 0x82000000.

Here are all the blobs I have:

> [nathan@nathanb-nuc ~/tmp] ls -l /lib/firmware | grep 8000
> -rw-r--r--  1 root root 1745176 May  5 18:32 iwlwifi-8000C-13.ucode
> -rw-r--r--  1 root root 2351636 May  5 18:32 iwlwifi-8000C-16.ucode
> -rw-r--r--  1 root root 2394060 May  5 18:32 iwlwifi-8000C-21.ucode
> -rw-r--r--  1 root root 2120860 May  5 18:32 iwlwifi-8000C-22.ucode
> -rw-r--r--  1 root root 2227284 May  5 18:32 iwlwifi-8000C-27.ucode

When this occurs I see a drop in throughput but the driver is able to carry on without manual restarting.
