I've got problem with Handbrake/ffmpeg. After ~5 minutes transcoding, the computer locks up. I'm fairly sure it's a kernel panic because caps-lock starts flashing.
There are a few logical questions about what to do and some about specific bugs but I'm really after one thing: what happened right before everything died?!
/var/log/kern.log and all I see around the time is me sticking in a DVD and then a few minutes later, the system booting up. No errors, no panic notice.
Is there any way to force panics to be logged? I'm fairly sure I can reproduce this (it's happened 100% of the times I've tried recently) so while I'd rather this "just worked", I'm happy enough to reboot a few times if it means I can find the cause of the panic.
