If I understand correctly, the module samsung-laptop can't be loaded in EFI mode. And this is "by choice". Are there any plans to support UEFI mode? Is anyone working on this or it will never be resolved? Thanks!

When doing a modprobe I get "No such device": # modprobe samsung-laptop FATAL: Error inserting samsung_laptop (/lib/modules/3.5.0-27-generic/kernel/drivers/platform/x86/samsung-laptop.ko): No such device I also tried a mainline build, as per https://wiki.ubuntu.com/KernelMainlineBuilds , and got the same result: # modprobe samsung-laptop FATAL: Error inserting samsung_laptop (/lib/modules/3.9.0-999-generic/kernel/drivers/platform/x86/samsung-laptop.ko): No such device # uname -a Linux sammy.lyte 3.9.0-999-generic #201304190456 SMP Fri Apr 19 08:57:39 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux I'm not sure if this is a regression from the previous fix or simply slightly different hardware.
