Hardware, Embedded Systems The title is pretty much self-explanatory - oh UEFI. "You can read more of what is known at H-Online, but the short summary is this: Samsung's UEFI implementation appears to be faulty. It was most likely tested with Windows only and found to work, but thorough testing with other operating systems doesn't appear to have been a priority - or perhaps a consideration at all. At present, the bug appears to affect Samsung 530U3C, 300E5C, NP700Z5C, NP700Z7C, and NP900X4C series laptops; if you have one of those laptops, we recommend you exercise extreme caution if you have a need to boot into a Linux environment."

I would love to know why you got voted down.

Ubuntu’s development team has worked with Samsung and identified the kernel’s Samsung-laptop driver as the prime suspect, and there are other workarounds proposed already to address the issue.


It does seem likely at this stage that you are correct.

Oh, come now, you already know why. I dared to criticize the amazing, wonderful, cannot possibly have any bugs, everyone should use it Linux. It's not cool to do that, even when it's true.

You probably got voted down for being a troll. If you bothered to look through the links, you would see that even if that driver were the problem, it was provided by Samsung. Second, its not the driver itself as much as the way that the driver interacts with the totally non standard way Samsung handles the BIOS. Like I mentioned above, writing to non permanent memory should not be able to brick a laptop.

Because, as usual, neither he nor you read.

The problem here is the device itself is doing things that only Samsung truly knows about, and it diverges away from any kind of reasonably expected behaviour. It's ACPI all over again. The Samsung kernel code was also built from Samsung's own code and yet it still fails.
