Hypervisor: Windows 2019 server Hyper-V (all update and drivers are the latest). VM: Hyper-V generation V2. Network adapter: Mellanox ConnectiX-3 EN 10G SR-IOV enabled, (Attachment 1). All VM-OSs were installed under the same conditions, (Attachment 2): mem: 6GB, HDD: 127GB; FS: Auto (ZFS) Guided Root-on-ZFS, (Attachment 3); ZFS: GPT (BIOS+UEFI), (Attachment 4); LAN: one HV-V2 network adapter, (Attachment 2); When we enable SR-IOV on the port, (Attachment 5), and load the Mellanox driver in the OS root@frw03v2:~ # kldload mlx4en everything works without problems as it should. Status of network connection is OK (Support SR-IOV active), (Attachment 6). Add to /boot/loader.conf to automatically load the ConnectiX-3 driver mlx4en_load=3D"YES" and reboot VM-OS. Result - Fatal trap on loading stage (Attachment 7-11). As a temporary solution to this problem, the pfSense community suggested this: in /boot/loader.conf add kern.cam.boot_delay=3D"10000" Indeed, all versions of the FreeBSD OS will now boot OK (with parameter kern.cam.boot_delay=3D"10000" in the configuration file /boot/loader.conf), but where is the guarantee that this focus makes the system stable under load? And yet, this focus stops working when parameter kern.cam.boot_delay is less than 1000. For example, if kern.cam.boot_delay=3D"500", then when booting the system - the same Fatal trap. --=20 You are receiving this mail because: You are the assignee for the bug.=
