After setting vm.pmap.la57=3D0 in /boot/loader.conf, I'm able to boot and run some operat= ing systems. FreeBSD, OpenBSD, and debian 13 trixie seem to work fine inside bhyve. Installing Fedora Workstation 43 and Arch Linux from 2025-11-01 ISO works f= ine for the installation (based on the 6.17-xx kernel version). Once the system= in the VM updates to 6.18.xx kernel version, the kernel panics. Alpine linux 3= .2 won't even boot because it uses the 6.18 kernel by default. I've attached a screenshot of the alpine kernel panic when first starting. Both 6.17 and 6.= 18 report RDSEED2 broken, but only 6.18 seems to fail to boot. As a test, I'm' able to run everything without issue on a Ryzen 9 system (s= ame FreeBSD 15/bhyve/vm configuration with linux-zvol).=20 I have not yet had time to attach gdb to the failing bhyve VMs to figure out what's happening on the EPYC system. --=20 You are receiving this mail because: You are the assignee for the bug.=
