Lenovo, Other Laptops with Corrupted BIOS after Latest Canonical Install
The reports are mostly concerning Lenovo laptops. However, other vendors may be affected as well, as suggested but ongoing reports.
The issue resides in the Intel ISPI driver in Linux 4.13 kernel which corrupts the BIOS for specific laptop motherboards. Thus, Canonical is moving forward to disable the Intel ISPI drivers in their kernel builds, researchers say. Fortunately, the company’s hardware enablement team has said this workaround. However, it won’t do much if the BIOS is already corrupted.
Users should note that an updated Ubuntu 17.10 release with the fixed kernel is forthcoming. But currently the download is discouraged due to issues on some Lenovo laptops:
The download of Ubuntu 17.10 is currently discouraged due to an issue on certain Lenovo laptops. Once fixed this download will be enabled again.
