I could confirm that setting vm.pmap.la57=3D0 in boot/loader.conf on HP ser= ver with EPYC CPU helped to have bhyve working. I have there installed FreeBSD 15.1 Stable and it runs from half of April to today without any crash. CPU is: hw.machine: amd64 hw.model: AMD EPYC 9115 16-Core Processor hw.ncpu: 32 hw.machine_arch: amd64 Server is HP Proliant DL325g11 with latest firmware (from April 2026) I have ther 2 VMs now with Windows Server 2025 Standard and it is running nicely and is stable. Next step will be to switch from stable to release. --=20 You are receiving this mail because: You are the assignee for the bug.=
