** Description changed:

  Description: An update to linux kernel on Ubuntu 17.10 that enabled the
  intel-spi-* drivers made Insyde BIOS unusable. Main issues were Settings
  being not stored, USB Boot impossible and EFI entries read-only.
  Fix: The issue was fixed in Kernel Version 4.13.0-21. But previous
  affected machines still suffered from a broken BIOS.
  Repair: Boot Linux and Install Kernel Version 4.14.9. Reboot into Linux
  and BIOS should be restored to a working state.
  Test Case: Fix has been verified by our HWE team on affected hardware.
  Regression Potential: Minimal, it's unlikely anyone is actually doing
  anything which requires this driver.

  Original Description:
  Basically on Lenovo Y50-70 after installing Ubuntu 17.10, many users
  reported a corrupted BIOS.
  It's not possible to save new settings in BIOS anymore and after
  rebooting, the system starts with the old settings.
  Moreover (and most important) USB booting is not possible anymore since
  USB is not recognized. It's very serious, since our machines do not have
  a CDROM.
  Lenovo forums at the moment are full of topics regading this issue.
  Thank you!!
