Matthew Garrett Has a Fix To Prevent Bricked UEFI Linux Laptops

Posted by timothy on from the and-it-can-be-yours-for-free dept.

hypnosec writes "UEFI guru Matthew Garrett, who cleared the Linux kernel in Samsung laptop bricking issues, has come to rescue beleaguered users by offering a survival guide enabling them to avoid similar issues. According to Garrett, storage space constraints in UEFI storage variables is the reason Samsung laptops end up bricking themselves. Garrett said that if the storage space utilized by the UEFI firmware is more than 50 percent full, the laptop will refuse to start and ends up being bricked. To prevent this from happening, he has provided a Kernel patch."

    ---The UEF Interface seems to work just fine with Win OS and iOS. How is that a bios problem?

    Samsungs implementation of UEFI is the problem, not the UEFI specification. No, it's not a 'bios' problem, UEFI replaced bios, but Samsung seems to have done something odd in their implementation of UEFI.

    "---Gee wonder why the great mass migration to Linux hasn't happened?

    Well sure, that has always been an issue. Linux apparently isn't important enough for companies to bother testing for it, which means it only works with contrived hacks, which means no one uses it, which means companies don't think it's important enough to bother testing for it.
