I'm so sorry. It's K8T-Master2.

And I read "ACPI debugging" handbook, just Nate Lawson said.

Then...

Oh My Goodness, causing problem is my USB mouse ( and my BIOS setting).
I've never thought about USB affects kernel before USB driver was loaded.

Now, I've just finished setup that machine and E-Mail client, and read
your mail.

Thanks for your reply.


But, sometimes I got Fatal trap 12( in swapper) at another boot sequence.
(sometime I changed USB connection, replaced kernel, and so on)

Reboot or Turn off and on the machine is my work around, now.
(It works! :-P )


I'll re-read ML archive to avoid sending silly question to ML again.

THX
