The other 17.10 editions seem to be fine, so are other Debian-based variants, and many other distros such as openSUSE and Fedora. In case you're wondering, replacing the CMOS battery does not solve the problem. None of the above procedures are for the faint of heart and could further complicate the issue. Right now, the only way out of this mess is to either reflash the BIOS (Lenovo does not have a Linux BIOS flashing tool), remove the BIOS chip if possible (mostly unlikely), or replace the whole motherboard. The company is now planning to re-release 17.10 without the said driver. Although the Intel-SPI driver is not part of the standard Linux kernel, Canonical has included a modified version of the driver in the kernel. This can have serious repercussions such as not being able to change boot options during startup, or in the worst case, a corrupted BIOS leading to a bricked laptop.
Reading through the bug tracker reveals that the Intel-SPI drivers in the kernel have been shipped before finalizing leading to the affected BIOSs becoming write-protected i.e. Lenovo forums at the moment are full of topics regading this issue. It's very serious, since our machines do not have a CDROM. Moreover (and most important) USB booting is not possible anymore since USB is not recognized. It's not possible to save new settings in BIOS anymore and after rebooting, the system starts with the old settings. The original description of the bug report, which can be found here, reads -īasically on Lenovo Y50-70 after installing Ubuntu 17.10, many users reported a corrupted BIOS. Following the gravity of the complaints, Canonical has temporarily halted seeding downloads of Ubuntu 17.10 desktop and said that a fix is being worked upon. the BIOS, or more precisely the UEFI, is no longer able to save settings, not being able to exit the BIOS settings, or even not being able to boot from USB. Users complain of a host of firmware related problems after installing the OS viz. The affected laptops primarily included Lenovo models and a few ones from Acer. A bug report filed on Ubuntu's bug tracker, Launchpad, has many users of the popular free OS complaining about corrupted BIOSs after updating their notebooks to the latest Ubuntu 17.10 'Artful Aardvark' release.
