Kernel log when vt console doesn't fit. none

Description Villy Kruse 2023-11-15 14:39:28 UTC
1. Please describe the problem:

Switching to the vt console (ctrl-alt-F4) gives the vt console and I can log in.
When filling up the screen, the last lines is not is way below the bottom edge
of the screen.

I have the option "video=1280x720" on the kernel command line, and I have it
because the characters on the screen would be way too small to read.
The default "1920x1080" works quite a bit better, but the last line is still
below the edge of the screen.

2. What is the Version-Release number of the kernel:

kernel-6.5.11-300.fc39.x86_64 has the problem
kernel-6.5.10-300.fc39.x86_64 does not have the problem and
all version before that also not.



3. Did it work previously in Fedora? If so, what kernel version did the issue
   *first* appear?  Old kernels are available for download at
   https://koji.fedoraproject.org/koji/packageinfo?packageID=8 :

kernel-6.5.11-300.fc39.x86_64 is the first version with the problem

4. Can you reproduce this issue? If so, please provide the steps to reproduce
   the issue below:

Always.  

5. Does this problem occur with the latest Rawhide kernel? To install the
   Rawhide kernel, run ``sudo dnf install fedora-repos-rawhide`` followed by
   ``sudo dnf update --enablerepo=rawhide kernel``:

Did not try yet

6. Are you running any modules that not shipped with directly Fedora's kernel?:

Oracle Virtual box, but the I am running on bare metal.  I might test without these
modules.

7. Please attach the kernel logs. You can get the complete kernel log
   for a boot with ``journalctl --no-hostname -k > dmesg.txt``. If the
   issue occurred on a previous boot, use the journalctl ``-b`` flag.



Reproducible: Always

Kernel log when vt console doesn't fit.

Comment 2 Villy Kruse 2023-11-15 15:04:25 UTC
Without the Oracle VirtualBox modules loaded the problem goes away.
I have to be sure they were not loaded as just unloading them didn't
help.

Comment 3 Villy Kruse 2024-02-16 07:27:25 UTC
The problem seems to have fixed itself, somehow.
