EC is the root cause, and it's not optional.  You need it with acpi enabled.

I think the actual error is here:

That is type SYS_RES_MEMORY, which seems bogus (should be IO ports).
Can you send ASL in private mail?

acpidump -dt | gzip -9c > my.asl.gz

Also, can you send dmesg from a successful 6.2 boot?  You can use a live
CD like FreesBIE to avoid installing it.
