Thanks.
On the other hand, I really wonder (and suspect) whether the problem isn't
really the freezer or even the kernel resume ordering, but simply an ACPI
internal resume ordering thing.
Doesn't ACPI have per-device "WAK" calls anyway? Shouldn't we just call
those _individually_ as we walk the device tree (perhaps in the
"early_resume" stage) rather than calling them all in one chunk?
