Hi everyone!

A boot-ed with verbose mode, and if i want to change the brightness i saw
on dmesg: ( brightness down with key ):
acpi: bad write to port 0x080 (32), val 0x1d
or ( brightness up with key )
acpi: bad write to port 0x080 (32), val 0x1c

I tested with other dsdt file from google acer acpi, nothing changed:
http://aceracpi.googlecode.com/svn/trunk/dsdt/acer/extensa/

I installed FreeBSD-Current to an usb key and booted. The error is the
same with brightness control.

Anyone has an idea wath wrong?

Thanks ours help!
Peter
