Comment 1 Dominik Mierzejewski 2017-02-06 09:27:39 UTC

Happens on every boot. Could be related to this device (iTec PCE2S1P, http://www.i-tec-europe.eu/?t=3&v=103):

Comment 3 Dominik Mierzejewski 2018-06-08 09:28:37 UTC

It looks like this was fixed before kernel 4.13.13-200.fc26.x86_64, which is the oldest I still have boot logs from (2017-11-17), so closing.
