After reluctantly switching from amd64 to i386, I also have garbled consoles. The driver seems fine apart from this one problem when I stop X. I've only noticed it on Ctrl-Alt-F1 or after issuing a "shutdown -p now" command. It looks like the console is still alive but it's so distorted I can't make anything out.
This sync problem wouldn't physically damage an LCD screen, right? I seem to recall CRTs could get severely borked by this sort of thing.
Unfortunately I'm not able to generate a crash dump. Although I can cause what looks like a kernel panic [bold white text, lots of it], I can't be sure because a) I can't make it out and b) it doesn't leave a dump behind for savecore.
So, 'fraid this is the best I can do for now:
% sysctl hw.nvidia.version
hw.nvidia.version: NVIDIA UNIX x86 Kernel Module 100.14.11 Wed Jun 13 15:15:08 PDT 2007
% sysctl hw.nvidia.cards.0.model
hw.nvidia.cards.0.model: GeForce Go 7600
% uname -rims
FreeBSD 6.2-RELEASE-p7 i386 SMP-GENERIC
Let me know if any other info would be handy.
ps. please excuse the lack of nvidia-bug-report.log file. I do not seem to have nvidia-bug-report.sh on my system.
