https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=291935 Bug ID: 291935 Summary: Vidconsole (amd64 only) does now show anything on old hardware (MacBook2,1) Product: Base System Version: 15.0-RELEASE Hardware: amd64 OS: Any Status: New Severity: Affects Some People Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: rz@fabmicro.ru Recently I was trying to install 64-bit FreeBSD on my old MacBook2,1 (A1181 mid 2007, based on Intel Core2 Duo T7400 @ 2.16GHz) and I faced the following issued: right after loader boots the kernel and gives control to it, no more output is produced on video console. Last few lines on the screen I can see are: Start @ 0xffffffff80387000 ... Loading splash ok Yet system proceeds booting and Installer runs, keyboard works fine (I even can use Installer in the blind). The problem appears only on amd64 branch. On i386 branch vidconsole works fine and I was able to install FreeBSD sucessfully on this machine (although it's completely unusable due to lack of drm-kmod support in i386 branch). I tested it on a number of previous releases: 13.5-RELEASE, 14.3-RELEASE and 15.0-RELEASE - same effect on all of them. I tested booting from memstick and DVD images. A friend of mine has same issue on another old MacBook though I don't know which model exactly. Any ideas what to try to reveal the root of the problem ? I can dedicate some time to help resolve this issue (trace the kernel in DDB if necessary). Just need some instructions/directions. :) -- You are receiving this mail because: You are the assignee for the bug.home | help
