PSA: Intel Atom C2000 Chips Flaw Bricking Routers/NAS/Firewall devices that are powered by Linux, pfSense and FreeNAS
Intel’s Atom C2000 chips are bricking products, and it’s not just Cisco hit. From the theregister:
Intel’s Atom C2000 processor family has a fault that effectively bricks devices, costing the company a significant amount of money to correct. But the semiconductor giant won’t disclose precisely how many chips are affected nor which products are at risk. Coincidentally, Cisco last week issued an advisory warning that several of its routing, optical networking, security and switch products sold prior to November 16, 2016 contain a faulty clock component that is likely to fail at an accelerated rate after 18 months of operation.
Intel has “Silvermont” which is a microarchitecture for low-power Atom, Celeron and Pentium branded processors used in systems on a chip (SoCs) made by Intel. It includes:
- Avoton – SoCs for micro-servers and storage devices.
- Rangeley – SoCs targeting network and communication infrastructure.
A list of Intel atom models affected
If you have SoCs with the following model, you need to backup all your data and send it to OEM or Intel:
You can use the following command on FreeBSD/FreeNAS NAS server or pfSense router/firewall based to find out more about your cpu:
$ sysctl -a | grep -i hw.model
hw.model: Intel(R) Atom(TM) CPU C2750 @ 2.40GHz
Linux users try lscpu command to find out cpu model:
$ cat /proc/cpuinfo

These SoCs are popular in the FreeNAS, pfSense and DIY NAS home server for being cheap, low power, ECC ram and multiple SATA ports. The replacement is hard as the CPU soldered to the board on these systems. Contact the vendor for RMA:
Other vendors using Atom C2000 chips include Aaeon, HP, Infortrend, Lanner, NEC, Newisys, Netgate, Quanta, Supermicro, and ZNYX Networks.
