Right - when writing 0 there before restart, the led value is actually 8 after reboot, and the LED hardware is ON. This holds for both reboot and halt+poweron cycle. Maybe this is related to the "#define MAX_BRIGHT 0x07" (which is unused in samsung-laptop.c)? A bit confusing in the code - but your question hints for some other bug (to be solved differently). Tell me if I can help somehow, here. > What's the behavior on windows ? There is no windows available on this machine.
