Yeah, I'm seeing this too on my laptop. It's a change in the upstream
ACPICA code (see [1]):

1) ACPICA kernel-resident subsystem:

For the ASL Sleep() operator, issue a warning if the sleep value is
greater than 10 Milliseconds. Quick boottime is important, so warn about
sleeps greater than 10 ms. Distribution Linux kernels reach initrd in 350
ms, so excessive delays should be called out. 10 ms is chosen randomly,
but three of such delays would already make up ten percent of the
boottime.
