...I've added a new BZ:
https://bugzilla.kernel.org/show_bug.cgi?id=15856
and attached the console output I collected from:
ignore_loglevel acpi.debug_layer=0x2800001f acpi.debug_level=0x00000027
This took almost an hour to boot so adding all flags would not be
practical.
I don't see any attachments to that bug report.
CONFIG_ACPI_DEBUG=y with
acpi.debug_layer=0x20000000 maxcpus=4 should do it.
Also, the output from acpidump.

Hmm, I wonder why it didn't get put in? It was a gzipped text file.
I'll add the above as soon as I get back on the system. I *think*
this might be the relevant part. It repeats this sequence 1664 times:
