@Gionn, if you're still around, this bug seems to be a duplicate of bug 1862751, which will need your microcode signature info so that we'll be able to land a fix for you. The command is:

  $ dmesg |grep microcode

I'm expecting something like "microcode: sig=0x506e3, pf=0x20, revision=0xd6". Thank you.

Hi, I don't have access to the XPS anymore, but I remember that have been fixed a few weeks later by an update (not sure if dell bios or intel-microcode).

Cheers.
