Subject: 2.6.20-rc6-mm[2-3] ACPI issues

Hi Len,

On 2.6.20-rc6-mm2 my rx2600 wouldn't boot unless I reverted all changes
to drivers/acpi/tables.c. Nearly all major early boot detected ACPI tables
weren't discovered.  I never had time to resolve because 2.6.20-rc6-mm3
showed up. The -mm2 problem appears corrected but the machine now crashes in
acpi_init for -mm3. 2.6.20-rc6 and 2.6.20-rc6-mm3 boot logs are included
at end of email.

For 2.6.20-rc6-mm3 the HP internal simualtor for a NUMA machine is
getting a preposterous pxm value and subsequently MCAs in pxm_to_node
because of large pxm. It seems like table parsing is being done
incorrectly.

Nope this is the issue:

I doubt you'll want to apply this patch. It appears HP firmware has some
of the reserved field not initialized to zero. This results in the huge
pxm. Was the pxm size expanded with a recent ACPI spec revision? 

Well with this patch I can pursue the acpi_init panic on simulator.

rx2600 (2 CPU MP) and NUMA simulator (1 node and 4 cpus)  boot successfully
on 2.6.20-rc6.
