Is it mandatory to report Reserved Memory region to the OS? For example,
the IOAPICs memory-mapped addresses? Would that be a problem if Linux
kernel didn't see it be claimed as RESERVED?
It seems Linuxbios doesn't claim any memory regions as RESERVED.
Well, I have a problem.
The PPC code, which was working in November, is now no longer working.
I rebuilt the Sandpoint image using the same configuration file, but
now I just get garbage on the screen. To help me track this down, can
anyone who has made changes that are likely to have cause this, please
let me know.

Anyone know the status of all the Epia's working with V2?
When Linux has IOAPICs and Local Apics configured via an ACPI MADT
it will not read the mptable at all. It will reference mptable
information though and not find any bus.
Only way out seems to add a DSDT als well. Or whatever table it wants
It is really broken.
You are kidding. I put junk in the CVS server?
I guess he still need some time to figure out how to modify his mptable.c.

Usually we simply setup the local apic in virtual wire mode.
