Thank you for the test!
Try to set debug.acpi.max_tasks to 128 or even higher to get rid of the new ACPI

Additionally I would like to ask you to do the following test.
Please stop devd and then run it (as root) from command line as such devd -D -d.
Please check what event are reported by devd.  In particular I am interested in
ACAD events, but all high frequency events are important.
