[tlinux-users 00218] Re: Toshiba Satellite U400-138 and ACPI issues

Jakub,

Send me (by private mail) your DSDT table as I explained in a previous
mail. I remember I had my LEDs blinking when I tried calling all the
interesting ACPI methods in the TVAP device/section in my DSDT table.
With some help, they will be identical and then I can confirm that.

Regards,
Ilyes Gouta.
