More likely than not, this is an ACPI issue. I see that you have it enabled in your 2.6.1 kernel. Do you also have ACPI enabled in your 2.4 kernel? In a more general way, you should look for differences in ACPI configuration between 2.4 and 2.6. If there is no difference, I invite you to turn on debugging and possibly relaxed syntax too. Maybe it'll let you discover something. Trying 2.6.2 is also an option to consider, since it seems to have many, many ACPI fixes and improvements. Hope that helps, -- Jean Delvare http://www.ensicaen.ismra.fr/~delvare/
