dmesg output

I run Fedora 26 on an HP Spectre x360 Kaby Lake (w063-nr) with an Intel 8265 and iwlwifi crashes every ~9 seconds when using the wireless connection. Websites load very slowly, if they finish loading at all. At the same time I see high CPU usage by kworkers to the point my mouse pointer lags and Rhythmbox's audio output stutters (playing a local file). I also observe a lot of interrupts on /sys/firmware/acpi/interrupts/gpe17.

Looking at the firmware version in the dmesg output, I tried going back to firmware 21, but the problem persisted. I found https://bugzilla.kernel.org/show_bug.cgi?id=195299 but do not think it's the same, since the firmware I'm running (27.455470.0) should have the fix described there included, right?

Hi,

we already invested a lot of time to debug this one as you can in the bug I linked to this one. Unfortunately, we couldn't do much. You can read the details inside the bug I attached.

You can try to upgrade to kernel 4.13 to be able to load -31.ucode to see whether it behaves better.

I am marking this bug as duplicate for now.
We'll keep getting the updates you may write here.
