[SOLVED] Kernel console/VT: boot msgs cut at 80 chars

Hi all!

I got that cosmetic nuisance that the kernel console/VT is reset to 80 columns for a moment during boot with Devuan Beowulf on my Intel(R) Core(TM) i5-8250U CPU.

- grub screen is in screen res
- loading initramfs text after grub is in screen res
- following boot messages show up in screen res, but then column is reset to 80 (i.e.: cutted text below: 'udevd[457]: spec' and 'udevd[519]: fail')
- just a moment later the column is again reset to screen res

INIT: version 2.93 booting
[info] Using makefile-style concurrent boot in runlevel S.
[....] Starting hot-plug events dispatcher: udevd[    3.754574] udevd[457]: spec
. ok
[ ok [    3.813949] udevd[520]: failed to execute[    3.834440] udevd[519]: fail
[ ok ] Waiting for /dev to be fully populated...done.
[ ok ] Setting up keyboard layout...done.
[ ok ] Activating swap...done.

Is there anyone who knows what is setting the column to 80. Is there any kernel parameter for that evil driver not to reset the column to 80?!

I guess I have to do a video with the smartphone. :-)

Try adding your video driver module to the initramfs to get an early KMS start.

Add the name of the module (i915 for Intel) to /etc/initramfs-tools/modules and run

# update-initramfs -u -k all

That's it. Thank you!

JFTR, I added option i915.fastboot=1 to the module.
