Well, it boots but I get:

TBH, I like Rafael's suggestion in the other mail to stick with fixing
this in ACPI, especially this is an ACPI problem, not RCU. Well,
more or less: RCU could be taught to *not* do schedule_work() if
workqueue_init() hasn't happened yet but that's a tangential.
So, I'm going to bed. When I wake up, I want to see working fixes!
:-)))
Thanks dudes!
