I don't have an idea how this happens, but it sounds like an alignment
issue:
sizeof(struct acpi_device_id)=20
"struct acpi_device_id button_device_ids[]" contains 6 elements
144 = 6 * 24 = 6 * (3 * 8)
So it seems on ia64 with gcc 3.3.6 there's some 8 byte alignment of the
array members?
Sam and the ia64 maintainers Cc'ed - they might know better what's going
on here.
