https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D211651 --- Comment #8 from Don Lewis <truckman@FreeBSD.org> --- If I try to disable the AMD-V setting, Virtualbox complains "Invalid Settin= gs Detected". If I disable virtualization in the BIOS, Virtualbox only seems = to understand 32-bit guests. I hadn't gone spelunking in the .kmod source because the stack traces foole= d me into thinking that the code was not part of the .kmod. ASMXRstore() is called from CPUMSetGuestXcr0(PVMCPU pVCpu, uint64_t uNewVal= ue) here: <https://www.virtualbox.org/browser/vbox/trunk/src/VBox/VMM/VMMAll/CPUMAllR= egs.cpp>. Perhaps it just needs added calls to fpu_kern_enter() and fpu_kern_leave(). Interestingly I don't see any calls to ASMXSave(). --=20 You are receiving this mail because: You are the assignee for the bug.=
