--- Comment #1 from Marcel Moolenaar <mar...@freebsd.org> ---
If I can read the screen correctly, it looks like the resolution is 1366x768,
with a stride of 1366 and a color depth of 32 bits per pixel (or 4 bytes per
pixel).
The console output seems to be using a stride that's just wrong. Since the
stride is coming from UEFI, it's hard to think of a reason why the kernel would
do this.
Have you tried updating the firmware?
--- Comment #2 from Oliver Pinter <o...@freebsd.org> ---
Yes, today I updated to latest bios from HP, but the issue still exists.
How could I extract these information without serial port or change the
settings in loader or kernel?

loader with 'gop' command
--- Comment #4 from Marcel Moolenaar <mar...@freebsd.org> ---
(In reply to Oliver Pinter from comment #2)
I committed revision 287299 (-current), that adds a 'gop' command to the
loader. I attached a pre-compiled EFI loader with this command to this PR.
Can you run 'gop get' and 'gop list' and add the output to this PR?
Also: can you try different modes (if possible) and see if that makes a
difference?

Dmidecode output
--- Comment #7 from Douglas King <douglasking...@gmail.com> ---
I am having the same issue trying to install on an HP Elitebook 2540p.
The error happens at the same point shown in the video except the whole output
is "squished" in the top 5-10% of the disply.
The display changes with user interaction but none of it is viewable.
The text from the boot process remains unaffected.
Booting without EFI freezes slightly earlier in the boot.
'gop' only has one mode listed.
--- Comment #8 from Oliver Pinter <o...@freebsd.org> ---
The issue still exists and the same on most recent stable from 2016.01.18.
--- Comment #9 from Vaclav Mocek <next.little....@gmail.com> ---
I have the same issue with an older Lenovo Ideapad S205, where during the boot
the screen is garbled. I tested the snapshot 10.2-r293802 and 11-r293801, both
are failing. I had the same issue with Linux three years back - the video mode
was not set correctly even in Grub2 and workaround was to use the option
gfxmode, which overwrites the detected values. So, I suspect that the UEFI GOP
provides partly incorrect information and the efifb is not set correctly.
Unfortunately, I have no clue how to debug these thing on FreeBSD, any hint
would be welcomed.
