/var/log/dmesg
On boot up with kernel-4.18.2 the screen freezes with the
last line on the console showing :-
"fb: switching to inteldrmfb from VESA VGA"
The rest of the boot continues with partitions mounted, etc, and
dmesg saved to log file.
Was ok with kernel-4.18.16 (have not tried the ones in between)
and is also ok with 4.19.3 and 4.14.82.
This is repeatable, though on one occasion I got and extra line
on the console (of normal usb related information).
------------------------------------
Hardware:
Asus P7H55-M SI with Intel Core i5 processor
and Integrated Graphics [i915 driver].
Distro: Slackware-14.2, but with newer kernel.
------------------------------------
Will attach dmesg extract including trace.
I appreciate 4.18.y is going EOL so this is all a bit academic,
but I am reporting it in case it affects anything else.</pre>
