AVR54. System May Experience Inability to Boot or May Cease Operation
Problem: The SoC LPC_CLKOUT0 and/or LPC_CLKOUT1 signals (Low Pin Count bus
clock outputs) may stop functioning.
Implication: If the LPC clock(s) stop functioning the system will no longer
be able to boot.
Workaround: A platform level change has been identified and may be
implemented as a workaround for this erratum.
Status: For the steppings affected, see Table 1, “Errata Summary Table” on
page 9.
簡單說是 CPU 某幾個訊號可能出包，導致系統無法開機
而且沒辦法靠 Microcode / BIOS 更新解決，只能更換硬體。
Cisco 的公告比較詳細
http://bit.ly/2jZVHTm 預估使用18個月後, 有較高機率開始出現這情況,
也有提供有問題和正常的 revision 編號
如果機器在 2016/11/16 時還有保固，未來會幫你維修,
http://bit.ly/2jZUr2E 群輝只發聲明說正在調查，機器有問題的人可以提出RMA申請
