https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D213333 --- Comment #17 from Cameron <cam@neo-zeon.de> --- I've managed to work around this.=20 There's 2 issues here: 1. Rather than using an Opteron_* model in kvm for the CPU, etc. Use kvm64. Others may work as well. I believe this alone will Just Work if you haven't been building from source. 2. Did you build everything/anything from source? You probably don't want to set=20 'CPUTYPE?=3Dnative', etc in /etc/make.conf (or perhaps you can find somethi= ng "safe" to set it to?).=20 If you are building from source AND had CPUTYPE set to something like Opteron_*, you'll probably need to rebuild your *current* working version before you can attempt to switch the CPU model to 'kvm64'. An Opteron optim= ized build won't even boot if you set the CPU model to 'kvm64' IIRC. First, unset CPUTYPE if you have it set and then rebuild _everything_. Rebu= ild world, kernel, and ports. Once you've confirmed that everything still works (you can reboot, your daemons still come up, etc), you should be able to sw= itch your virtual CPU model to kvm64. Once your system runs with with kvm64 set, you can build the newer version = of FreeBSD that you want to move to. To be safe, try the newer kernel first (as you should in general anyway) to confirm that it's working without surprise= s. Seeing as how I found that much more than the kernel and the base system we= re affected, this could very well be a compiler regression for the Opteron tar= get. Anyway, hope this helps! --=20 You are receiving this mail because: You are the assignee for the bug.=
