As I said: I might be wrong, but I think the Armada simply is too old for a correct implementation of ACPI, it was build for APM. So, the problem is not FreeBSD, it's the Armada. > Please note that I'm not trying to diss FreeBSD in anyway for it being > broken as I understand the issues with the DSDT, AML, and ASL stuff, I > just want it to work. Other system would also show this problem, the fan never starts to work under Linux (tested FC3 a few weeks ago). I really don't know if it's possible to get ACPI+FreeBSD 5.x+Armada 1750 to work, I can only say that it worked perfectly with FreeBSD 4.x and APM. And I can say that FreeBSD+ACPI works great on newer notebooks (evo N160, IBM Thinkpad...). cu, Uwe
