[Bug 1734147] Re: Ubuntu 17.10 corrupting BIOS - many LENOVO laptops models

[Steve Langasek]

** Description changed:

  SRU Justification
  
  Impact: Many users are reporting issues with bios corruption with 17.10.
  This seems to stem from enabling the intel-spi-* drivers in the kernel,
  which don't appear to be ready for use on end-user machines.
  
  Fix: Disable this driver.
  
  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.

  Hi all,
  
  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!!
