Intel revealed in its Q4 2016 quarterly report that there were quality issues in the C2000 product family, which had an effect on the financial performance of the company's Data Center Group that quarter.{{cite news|last1=Alcorn|first1=Paul|title=CPU Failures Hurt Intel's Bottom Line|url=http://www.tomshardware.com/news/intel-cpu-failure-atom-processor,33538.html|access-date=7 February 2017|publisher=Tom's Hardware|date=31 January 2017}} An erratum named AVR54 published by Intel; state there is a defect in the chip's LPC clock, and affected systems "may experience inability to boot or may cease operation".{{cite news|last1=Hellstrom|first1=Jeremy|title=Intel's Atom C2xxx processors may just make like a banana and split|url=https://www.pcper.com/news/General-Tech/Intels-Atom-C2xxx-processors-may-just-make-banana-and-split|access-date=7 February 2017|publisher=PC Perspective|date=7 February 2017}}{{cite news|last1=Calburn|first1=Thomas|title=Atom C2000 chips are bricking products – and it's not just Cisco hit|url=https://www.theregister.co.uk/2017/02/06/cisco_intel_decline_to_link_product_warning_to_faulty_chip/|access-date=7 February 2017|publisher=The Register|date=6 February 2017}}{{cite web|title=Intel Atom Processor C2000 Product Family Specification Update|url=https://www-ssl.intel.com/content/dam/www/public/us/en/documents/specification-updates/atom-c2000-family-spec-update.pdf|website=Intel Atom Processor C2000 Product Family Specification Update|publisher=Intel|access-date=7 February 2017}} A workaround is available requiring platform hardware changes. The SoC failures are thought to have led to failures in Cisco and Synology products,{{cite news|last1=Kampman|first1=Jeff|title=Report: Some embedded Atom CPUs can brick their host systems|url=https://techreport.com/news/31398/report-some-embedded-atom-cpus-can-brick-their-host-systems|access-date=7 February 2017|publisher=Tech Report|date=7 February 2017}} though discussion of the C2000 as the root cause of failure has been reported to be under a non-disclosure agreement for many vendors.{{cite news|last1=Kennedy|first1=Patrick|title=The Intel Atom C2000 Series Bug – Why It is So Quiet|url=https://www.servethehome.com/intel-atom-c2000-series-bug-quiet/|access-date=28 February 2017|publisher=ServeTheHome|date=7 February 2017}}

Intel released a new C0 stepping of the C2000 series in April 2017 which corrected the bug.{{cite news|last1=Robinson|first1=Cliff|title=Intel Atom C2000 C0 Stepping Fixing the AVR54 Bug|url=https://www.servethehome.com/intel-atom-c2000-c0-stepping-fixing-the-avr54-bug/|access-date=25 April 2017|publisher=Serve the Home|date=23 April 2017}}

In July 2017 Intel published that a similar quality issue affects also Atom E3800 series embedded processors. The erratum named VLI89 published by Intel state, similar to issue with Atom C2000, that there is a defect in the chip's LPC clock and affected systems "may experience inability to boot or may cease operation".{{Cite web|url=https://www.intel.com/content/dam/www/public/us/en/documents/specification-updates/atom-e3800-family-spec-update.pdf|title=Intel Atom® Processor E3800 Specification Update|access-date=2018-04-13}} Issues extend also to USB bus and SD card circuitry and should happen "under certain conditions where activity is high for several years". In April 2018 Intel announced it is releasing a new D1 stepping to fix the issue.{{Cite web|url=http://qdms.intel.com/dm/i.aspx/BF417A50-F5AE-4179-8393-08083292AC0D/PCN116196-00.pdf|title=Product Change Notification 116196 - 00|date=2018-04-09}}

The LPC, USB and SD Card buses circuitry degradation issues also apply to other Bay Trail processors such as Intel Celeron J1900 and N2800/N2900 series;{{Cite web|url=https://www.intel.com/content/dam/www/public/us/en/documents/specification-updates/Celeron-J1900-N2807-N2930-IoT-SU-Addendum.pdf|title=Intel® Celeron® Processor J1900, N2807 & N2930 for Internet of Things Platforms Specification Update Addendum|access-date=2018-04-14}} also to Pentium N3500, J2850, J2900 series; and Celeron J1800 and J1750 series—as those are based on the same affected silicon.

Cisco stated failures of Atom C2000 processors can occur as early as 18 months of use with higher failure rates occurring after 36 months.{{Cite web|url=https://www.cisco.com/c/en/us/support/web/clock-signal.html#~faqs|title=Clock Signal Component Issue|website=Cisco|access-date=2018-04-14}}

Mitigations were found to limit impact on systems. Firmware update for the LPC bus called LPC_CLKRUN# reduces the utilization of the LPC interface what in turn decreases (but not eliminates) LPC bus degradation - some systems are however not compatible with this new firmware. USB should have a maximum of 10% active time and there is a 50TB transmit traffic life expectancy over the lifetime of the port. It is recommended not to use SD card as a boot device and to remove the card from the system when not in use.

It has been widely reported that Bay Trail CPUs (and possibly their derivatives including Airmont/Braswell/Cherry Trail) experience random freezes / lock-ups on various Linux kernels. Reference Linux [https://bugzilla.kernel.org/show_bug.cgi?id=109051 bug report 109051] on Kernel.org Bugzilla, first reported Dec-2015. Workaround seems to be setting the Linux kernel flag intel_idle.max_cstate=1, which while eliminating the system freezes/lock-ups, results in increased CPU power/battery usage by preventing the CPU from entering higher power-saving C-states. Systems running Windows-OSes apparently do not experience these lockup/freeze issues. The issue had been addressed in the commit [https://git.kernel.org/torvalds/c/a75d035fedbd "drm/i915: Disable preemption and sleeping while using the punit sideband"].

A potential fix is to set {{code|1=hw.acpi.cpu.cx_lowest=C1}} and {{code|dev.cpu..lowest}} via {{code|/etc/sysctl.conf}}.

14 nm Airmont architecture processors are also affected by the design flaws as noted in the Braswell Specification Update under CHP49 errata.{{Cite web|url=https://www.intel.com/content/dam/www/public/us/en/documents/specification-updates/pentium-celeron-n-series-spec-update.pdf|title=N-series Intel® Pentium® Processors and Intel® Celeron® Processors Specification Update|access-date=2018-04-15}} In addition to LPC and SD Card circuitry degradation issues those 14 nm designs also have issues with Real Time Clock (RTC) circuitry degradation, their USB buses are however not affected. Unspecified firmware changes are required to mitigate RTC circuitry degradation. Intel does not plan to release a new stepping for Braswell. Intel admitted the issue stating the impact on consumers depends on use condition.{{Cite web|url=https://www.servethehome.com/another-atom-bomb-intel-e3800-bay-trail-atom-vli89-bug/|title=Another Atom Bomb Intel Atom E3800 Bay Trail VLI89 Bug|date=2018-04-13|website=ServeTheHome}}
