I have an Acer Travelmate P653 = model MS2352 with an Intel HD4000 (I think) Gen 3 graphics card. = Unfortunately pciconf, and dmesg do not show useful information other = than intel gen3 graphics. This laptop doesn=E2=80=99t give me the = option to disable CSM. It also boots whatever is available whether EFI = only is selected or not. FreeBSD 10.1 worked on this laptop, and loaded = i915kms properly. PCBSD has always worked, and still works even with = their 11 CURRENT images which no longer use grub. Sometime after changes in FreeBSD 10-STABLE, 10.2 onwards, and recent 11 = CURRENT the resolution no longer sets properly when using UEFI boot. It = now boots with a 640x480 resolution, and kldload i915kms results in a = black screen. I have not been able to grab a debug log, or crash dump = even with all of the debugging features turned on. I cannot ssh into = the laptop when this panic occurs, and the screen is black so I can=E2=80=99= t really see what happened. I=E2=80=99m curious if there is anything = else I can do besides enabling dumpdev or kldload -v i915kms > = output.txt that doesn=E2=80=99t give me any detail. Nothing shows up in = /var/crash or whatever the directory was. I=E2=80=99ve noticed if I compile from PCBSD=E2=80=99s fork of FreeBSD = current source on top of FreeBSD it works. I have been unable to track = down the difference at this point. I=E2=80=99ve been working on it for = a few months but I have not figured it out. I would appreciate any help = I could get in tracking down the cause to fix the problem for others. I = can=E2=80=99t seem to find that it=E2=80=99s a problem for anyone else = however after months of research. I did find one interesting thing. If I mount the EFI partition, and = replace /mnt/efi/boot/bootx64.efi (boot1.efi) with loader.efi by cp = /boot/loader.efi /mnt/efi/boot/bootx64.efi i get full 1366x768 console = resolution. I can then use scfb at least if I delete the i915kms* = drivers to start X. I tested boot1.efi on a mac, and it of course sets the proper 1920x1080 = resolution it should. I am curious what the difference is between = boot1.efi, and loader.efi. Is a device id or something missing from = boot1.efi for my laptop to set the proper resolution? It=E2=80=99s it = the fact that I can=E2=80=99t disable CSM, and it=E2=80=99s somehow = booting non EFI? Can I remove certain things don=E2=80=99t force EFI = only, or somehow force FreeBSD to disable CSM? Can I somehow roll an = EFI only release of FreeBSD for further testing? If so what would I = need to remove, or disable? Does anyone have any suggestions on what I = could try to gather dump information as well regarding the i915kms = lockup? Joe Maloney
