I'd like to report one more instance of this bug. BUT perhaps more
importantly pass on a condition that seems to trigger these ACPI errors
at boot time (which you may or may not realize) and which might affect
your continued approach to fixing.
I use an old Dell t7400 and just recently decided to activate their TPM
(trusted platform module) in my bios. I had never received any of these
boot ACPI errors until I activated the TPM (which uses the broadcom LAN
chip for crypto key generation).
Immediately after activation, the ACPI errors unique to my system were
reported at boot through dmesg. Upon deactivation AND DISABLING the TPM
function (there are 2 distinct steps needed) the boot time ACPI errors
cease being reported.
