  • I used to see those on my kabylake XPS13 9360. I saw that error at boot and on every resume from November 2016 until Feb 4 when I installed an updated BIOS (file name XPS_9360_1.3.2.exe, sha1 8fea8ba38a5afccbc65436898d377324fdc60e7a).

    I would expect the 5520 to receive an updated BIOS to address the problem like the 9360.

  • I have heard the same from other users like you. Hoping Dell will release an update soon

  • The Problem still occurs with BIOS Version 1.2.4

  • The Problem still occurs with BIOS Version 1.5.0
