Hi Corentin,

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.

Which bugzilla? Sorry, I'm not an ACPI specialist.

Cheers,
Sebastian
