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 <op@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? --- Comment #3 from Marcel Moolenaar <marcel@FreeBSD.org> --- Created attachment 160509 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=160509&action=edit loader with 'gop' command --- Comment #4 from Marcel Moolenaar <marcel@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? --- Comment #5 from Douglas King <douglasking215@gmail.com> --- Created attachment 162834 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=162834&action=edit BIOS information dmidecode output --- Comment #6 from Douglas King <douglasking215@gmail.com> --- Created attachment 162835 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=162835&action=edit Dmidecode output --- Comment #7 from Douglas King <douglasking215@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. -- You are receiving this mail because: You are the assignee for the bug.
