Additionally the crash happens more often with enabled passthru, but also without. The two devices in vm-bhyve_Windows.conf are a GPU (AMD RX580) and a USB-Hu= b. Changed to another tty to see some messages, restarted the Windows Guest, z= ero messages but reliable freeze and hard reset. This is not happening with Linux/BSD/OpenVMS/9Front/omniOS really just with Windows10/11 and the corresponding server variants. To me it "smells" a bit, but not really like that Forum entry: https://forums.freebsd.org/threads/bhyve-vm-stuck-when-passthru-enabled.928= 54/ --=20 You are receiving this mail because: You are the assignee for the bug.=
