--- Comment #87 from paul idle (pid...@gmx.com) ---
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.
