2.6.20-rc6-mm2 git-acpi.patch contained only the acpi_table_parse()
fix for bugzilla-7465.  The version of the patch that made -mm2 had a flaw
where if the HPET were not connfigured, it would BUG_ON() due to a NULL
handler it didn't expect -- and this generally happened before VGA was enabled.
That bug got fixed, and also bugzilla-7465 is not in -mm3 -- which explains
why it went away.

That part I can't explain.

Yep.
The original code was programmed to the Microsoft SRAT spec -- which
identifies itself as version 1.  The new code is talking to ACPI 3.0 SRAT spec
which identifies itself as version 2.

In the SRAT memory affinity structure, the difference is that the proximity_domain
is now 4-bytes instead of 1.

We need to be checking for the SRAT revision and handling both revisions.

Might be safer to build w/o NUMA until we get the SRAT fixed.

Hmm, we seem to have touched a register that isn't there.

Assuming building w/o NUMA doesn't somehow magically fix this...
build with CONFIG_ACPI_DEBUG=y and boot with acpi_dbg_level=0xffffffff
and acpi_dbg_layer=0x2 and that should tell us everything about ACPICA's
attempt to talk to hardware registers.

thanks,
