Hello,
I'm forwarding a message from Michal Stanek who found some problems wit
this commit. Please see below:
-------------------------------------------
I'm getting a lot of ACPI error messages on ThunderX (arm64). The kernel
also panics before it gets to prompt.
Running bisect pointed to this patch as the culprit.
Removing acpi from GENERIC configuration fixes the issue.
Here is the boot log:
FreeBSD/SMP: Multiprocessor System Detected: 48 CPUs
random: entropy device external interface
ACPI: Table initialisation failed: AE_NOT_FOUND
