dmesg | tail -n 100

Hi,

I have encountered an error on my Lenovo Thinkpad P53 when trying to get the wifi to work.

The firmware version is `55.d9698065.0 cc-a0-55.ucode op_mode iwlmvm`.

I can scan and connect but it disconnects after ~30 seconds.

The error I receive is this:

Pity nobody is looking at fixing https://bugzilla.kernel.org/show_bug.cgi?id=203709 or https://bugzilla.kernel.org/show_bug.cgi?id=205299 (which seems to be a duplicate of 203709) that loos to be related to this.
