https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=234625 Bug ID: 234625 Summary: iMac early 2008 garbled screen during install from USB stick Product: Base System Version: 12.0-RELEASE Hardware: amd64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: jwb@freebsd.org After loading text, data and syms, the screen switches modes and becomes unreadable. After booting completes you can make out a blue background and whitish stripe across the middle of the screen which would be the first menu. By booting into OS X I determined that the iMac has a Radeon GPU. I was able to get around the problem as follows: 1. After booting to the first menu, type Ctrl+Alt+F4 to get to a shell. The screen is still garbled here, so this alone does not help. 2. Blindly type "kldload radeonkms". The screen then resets to a readable state. I have not tried 11.2 on this machine, but would be willing to if it might help isolate the issue. -- You are receiving this mail because: You are the assignee for the bug.
