PSA: Intel Atom C2000 Chips Flaw Bricking Routers/NAS/Firewall devices that are powered by Linux, pfSense and FreeNAS

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:

  1. Avoton – SoCs for micro-servers and storage devices.
  2. Rangeley – SoCs targeting network and communication infrastructure.
