--Sig_/vem6_de7wbPvr_47rC1cr2o Content-Type: text/plain; charset=US-ASCII Content-Transfer-Encoding: quoted-printable Hi, since the last bios-update (AMD Ryzen Threadripper 1950X on Asus ROG STRIX x399-E) I get the following message when starting a Windows 10 Guest on FreeBSD 11.1/amd64:=20 wrmsr to register 0x49(0x1) on vcpu x wrmsr to register 0x49(0x1) on vcpu x wrmsr to register 0x49(0x1) on vcpu x wrmsr to register 0x49(0x1) on vcpu x The message will be repeated endless (x is the number of the vcpu). Despite this message, the guest is running fine. I don't have any performance issues at the moment. Prior to this bios-update the message appears only once (or twice?) for every vcpu. Attached you find the way I start bhyve: bhyve -c8 -m 16G -H -w \ -s 0,amd_hostbridge \ -s 3,ahci-cd,/home/frank/bhyve/null_dvd.iso \ -s 4,ahci-hd,/dev/zvol/zroot/win10disk0 \ -s 10,virtio-net,tap0 \ -s11,fbuf,tcp=3D0.0.0.0:5900,w=3D1600,h=3D900 \ -s 30,xhci,tablet \ -s31,lpc \ -lbootrom,/usr/local/share/uefi-firmware/BHYVE_UEFI.fd win10 I use "hw.vmm.topology.cores_per_package=3D4" in /boot/loader.conf and a "custom" vmm.ko (https://reviews.freebsd.org/D13780) since January. When starting bhyve without "-w", the guest freezes while booting. But I think this has to do with another issue https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D219343 The changelog from Asus says: Update AGESA 1.0.0.5 recommend to keep C-state [enable] Does anyone have an idea how to solve this issue?
