My Lenovo G50-80 is also fixed by updating to 4.14.9. I've updated the Bug Description so anyone facing the issue can repair their devices.
** Description changed: - SRU Justification + 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. - 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: The issue was fixed in Kernel Version 4.13.0-21. But previous + affected machines still suffered from a broken BIOS. - Fix: Disable this driver. + 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. --- - 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.
