So ignoring ACPI_DEBUG=y for the moment, I put in a WARN_ON() in the
unaligned trap handler to get some stack traces when the unaligned
access happened.
Here's the boot log from that (note that there are perhaps more
unaligned
accesses than this, but the kernel rate limiting code kicks in at five
messages).
