https://bugzilla.kernel.org/show_bug.cgi?id=204209 Bug ID: 204209 Summary: kernel 5.2.1: "floating point exception" in qemu with kvm enabled Product: Virtualization Version: unspecified Kernel Version: 5.2.1 Hardware: x86-64 OS: Linux Tree: Mainline Status: NEW Severity: high Priority: P1 Component: kvm Assignee: virtualization_kvm@xxxxxxxxxxxxxxxxxxxx Reporter: antdev66@xxxxxxxxx Regression: No After updating the kernel from 5.1.17 to 5.2.1, when I use the g++ compiler in qemu with kvm enabled, often the compiler launched in the guest for compile my sources ends with this error: "exception in floating point". Moreever it is not possible to update the bsd system because the process (that use g++ compiler) exits with the same error. Same thing for some system utilities, like "pkg update". But if I boot the system with the previous 5.1.17 kernel and launch qemu, as indicated above, everything works fine and I don't detect errors. Command line is: /usr/bin/qemu-system-x86_64 -k it -machine accel=kvm -m 4096 -no-fd-bootchk -show-cursor -drive file="vmdragon.img",if=ide,media=disk -boot once=c,menu=off -net none -rtc base=localtime -name "vmdragon" -smp 8 -vga std -device qemu-xhci,id=xhci I can't test without kvm because the process is very slow, but I think the problem could be in some changes made to the kvm module.
