I thought it does for the video driver/backlight control. The strange thing is that the issues start directly after loading the driver. Perhaps it has to be blacklisted for this model. Kernel log: samsung_laptop: detected SABI interface: SwSmi@ samsung_laptop: Backlight controlled by ACPI video driver ACPI Warning: 0x000000000000efa0-0x000000000000efbf SystemIO conflicts with Region \_SB_.PCI0.SBUS.SMBI 1 (20120711/utaddress-251) ACPI: If an ACPI driver is available for this device, you should use it instead of the native driver Where are the custom ACPI drivers in the kernel tree if not in drivers/platform/x86 ? E.g. "eeepc-laptop" registers something like a custom ACPI driver if I see that right. > This looks like ACPI issues, please file a bug on bugzilla, but first > thing, check for bios updates :).
