I have two 4 disk enclosures: Mediasonic ProBox 4 Bay 3.5' SATA HDD Enclosure – USB 3.0 & eSATA (HF2-SU3S2) NexStar HX4 - NST-640SU3-BK and both have 4 disk on them, and not all disk are equal. The issue comes when I plug the probox usb3 enclosure on the system. I can't even read the /var/log/message, it crashes very quickly. I can see on the boot process up to the point where the second enclosure comes to be loaded. The 4 disk are shown on the dmesg/console, and then a core dump happens, the boot process goes to the debug screen and a restart happens like a flash. The motherboard is a Intel® Desktop Board D525MW running 8GB RAM. All disk use ZFS, 4 or 5 zpools, one raidz, one mirror and two or three single disk pools.

How can I debug this? I have no idea. I have to use two machines to run all those disks, and I would really like to have just one for it. Can it be the amount of RAM? The other box is and APU2 from PCEngines and have 4GB ram. apu2 uname -a: FreeBSD yyy 11.1-RELEASE-p4 FreeBSD 11.1-RELEASE-p4 #0: Tue Nov 14 06:12:40 UTC 2017 root@amd64-builder.daemonology.net:/usr/obj/usr/src/sys/GENERIC amd64 I tried to plug the Vantec hardware on the apu2 box, but there it would not panic, but won't load all vantec disks neither. I really run out of ideas here :( thanks. -- "We will call you Cygnus, the God of balance you shall be."
