Bug description:
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!!
