https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=213155 --- Comment #24 from Oliver Böttcher <marvin0815@gmail.com> --- (In reply to Martin Waschbüsch from comment #23) > When you say that "enabling all features and model=qemu64 booted", does that include xsave? Yes. The long snippet exposes all features of Opteron_G5 including xsave. The only difference I see is that the CPU is reported as QEMU Virtual CPU version 2.5+. My ultimately wild guess is that FreeBSD is doing some optimizations based on the reported CPU like workarounds for bugs which is necessary for bare metal but crashes virtualized environments not having these bugs. -- You are receiving this mail because: You are the assignee for the bug.help
