NetBSD 7 acpi problem on Sun Fire X4600M2

[Helge Muehlmeier <H_Muehlmeier%gmx.de@localhost>]

Hello,

I want to run NetBSD 7 amd64 on a Sun Fire X4600M2.

If I try to install the system with acpi enabled the boot process hangs 
and nothing happens anymore. I'm able to install the NetBSD 7 without acpi.

I can run the computer without acpi enabled too.

My problem is that NetBSD 6_STABLE has no problem with acpi enabled. But 
I have a PCIe card with two M.2 sata ssd installed and NetBSD 6 isn't 
able to use that controller/disks. I got error messages with that.

NetBSD current also doesn't run with acpi enabled.

The system have AMD Opteron processors installed... Is it possible that 
there was sometinkg changed in the default kernels?

Does somebody have an idea how to get acpi working with NetBSD 7?


Greetings,

Helge
