We bought 3 6501 2 years ago (for a redundant firewall/router +
HAProxy). One of them died after a year, got replaced under warranty and
died again 3 months later, another died just a few weeks agos, and the
last one suffer from this puzzling "error led" problem (works until
reboot, "sometimes" boot later, ...).

I think there is definitively an hardware/BIOS issue with the board, I'm
confident that the problem doesn't come from the power supply or an
overheating from the CPU.

As others I'm disappointed that Soekris is so silent on this issue,
especially if the root cause doesn't come from a broken bios/PCB
design/...

As we run FreeBSD, we finally replaced those boxes with a RCC-VE 4860 1U 
from Netgate (https://www.netgate.com/products/rcc-ve-4860-1u.html)
