Extract from dmesg showing traces

Three traces during boot up (before networking start up and well before
X windows was started). Subsequently there was a slow response to keyboard
inputs most of the time, though the system was just usable with patience.

CPU usage was normal and the display appeared normal.

There was one further trace later on.

After a reboot everything was ok. I had installed linux-5.2.10 three days
earlier and had no previous problem. I cannot reproduce the bug.

------------------------------------
Hardware:
  Asus P7H55-M SI with Intel Core i5 processor
  and Integrated Graphics [i915 driver].
Currently using a keyboard connected to a PS/2 keyboard port and using a
USB connected mouse.
Distro: Slackware-14.1, but with newer kernel.
