Sometimes FreeBSD boots fine but one of the NVMe drives is not visible (i.e. dmesg grep shows only one NVMe). When it doesn't work it boots up to the point of enumerating drives (SATA, USB, NVMe). Then it stops at the first NVMe and reboots. The funny thing is that very often it's enough to pull out one of the cards and put it back in. Then the system boots fine with all three cards. I had that a few times. Once it's booted it works, I can restart the system and it boots every time. As soon as I power off, unplug from the power main, wait a few minutes and power it on again, the issue comes back - can't boot as NVMe can't be enumerated. I though it might be caused by the hardware being too cold. I left the server once overnight but it didn't boot up, it was trying and restarting the whole night. GregJ
