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? --- Comment #3 from Marcel Moolenaar <mar...@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 <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? --- Comment #5 from Douglas King <douglasking...@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 <douglasking...@gmail.com> --- Created attachment 162835 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=162835&action=edit 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. --- Comment #10 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.

In CSM mode, "gop get" returns only one mode, with much larger frame buffer size compared to native (non-CSM) boot for some reason: > OK gop get > mode 0: 1024x768x32, stride=1024 > frame buffer: address=c0000000, size=1000000 > color mask: R=00ff0000, G=0000ff00, B=000000ff In CSM mode, laptop initializes itself with 1024x768 screen resolution and FreeBSD boots fine. Now, in native (non-CSM) mode, four modes are reported: > OK gop get > mode 0: 1366x768x32, stride=1366 > frame buffer: address=c0000000, size=420000 > color mask: R=00ff0000, G=0000ff00, B=000000ff > > OK gop list > mode 0: 1366x768x32, stride=1366 > mode 1: 800x600x32, stride=800 > mode 2: 1024x768x32, stride=1024 > mode 3: 640x480x32, stride=640 However, only modes 2 and 3 allow to have normal (non-smashed) console. Booting in other modes looks exactly like on the video clip attached earlier. --- Comment #12 from Alexey Dokuchaev <da...@freebsd.org> --- Tonight I've played with it a bit more. 1. I've discovered that in Linux Matthew Garrett had patched EFI framebuffer size calculation instead of trusting what firmware provides back in 2012 (https://lkml.org/lkml/2012/7/27/407). I've made a similar change to our code, but it didn't fix the problem: > efifb->fb_size = efifb->fb_height * efifb->fb_stride * 4; Side note: Linux is setting their si->lfb_linelength = pixels_per_scan_line * 4; while we use it as is: efifb->fb_stride = info->PixelsPerScanLine; I wonder why... 2. I've tried booting rather old ubuntu-11.04-desktop-amd64.iso in native UEFI mode and got very similar screen distortion in GRUB; it didn't boot further and I don't have a more recent Ubuntu version at my hands at the moment. 3. OS X Mavericks on HP Probook/Elitebook laptops guide (http://www.insanelymac.com/forum/topic/293842-guide-mavericks-on-hp-probookelitebook-laptops-with-clover-uefi-bootloader/) also mentions this problem under "Known issues" as item number one: "Distorted bootscreen with 7-series laptops using 1366x768 display + UEFI native (without CSM) setting. Changing Clover resolution to 1024x768 can fix it." At this point I tend to believe that this is a problem on HP side, and I'm not sure if it can be efficiently mitigated other than sticking to 1024x768 (mode 2). Any further ideas are certainly welcome. --- Comment #13 from Kubilay Kocak <ko...@freebsd.org> --- Test comment --- Comment #14 from bel3a...@aol.com --- I have the same problem with an HP Elitebook 8470p --- Comment #15 from Eitan Adler <ead...@freebsd.org> --- For bugs matching the following conditions: - Status == In Progress - Assignee == "b...@freebsd.org" - Last Modified Year <= 2017 Do - Set Status to "Open" --- Comment #16 from Mark Linimon <lini...@freebsd.org> --- Is this still a problem as of 12-ALPHA? --- Comment #17 from Alexey Dokuchaev <da...@freebsd.org> --- Yes, it is still a problem. Current work-around is to add "gop set 2" to /boot/loader.rc.local (this forces 1024x768). The problem is not very important because once KMS modules are loaded, the screen switches to native resolution. -- You are receiving this mail because: You are the assignee for the bug. _______________________________________________ freebsd-bugs@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-bugs To unsubscribe, send any mail to "freebsd-bugs-unsubscr...@freebsd.org"
