Description of problem:
File issues here which appear with the -bigmem kernel which don't
appear with non -bigmem kernels.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. run bigmem
2. find bug
3. report not repeatable with normal kernel bugs here.

BIOS A02, possibly others) hang at kernel initialization of APM with
-bigmem versions of
These systems/kernels succeed if apm=off is passed. I'm investigating
if this is an APM BIOS bug, as these laptops don't generally ship with
APM-enabled operating systems, but ACPI.
wli has told me privately that his IBM ThinkPad X21 does *not* fail
with CONFIG_HIGHMEM64G=y and CONFIG_APM=y.
