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 per cent full the laptop will refuse to start and end up being bricked. To prevent this from happening he has provided a Kernel patch that would ensure that Linux does not fill up more than 50 per cent of UEFI firmware's storage space."
