Maybe the memo= ry regions it writes to aren't mapped correctly or something=2E Silly debug idea: log all memory access initiated by acpi in FreeBSD and N= etBSD and compare :) Less silly idea: can someone who's really really familiar with FreeBSD's a= cpica integration take a look at the RPi4 dsdt already?? Please??
