I have disabled EARLY_AP_STARTUP (due to an issue in a local bge WOL patch, 
which I have yet to resolve). My kernel boots, so EARLY_AP_STARTUP is

After your comment I thought that this is another case of an update requiring
EARLY_AP_STARTUP option, but apparently the kernel config on this box does
contain it already.

Seems like it's triggered by the code that's supposed to limit execution time of
loops.

Hi Jung-uk,

After this change, the test machine booting in bhyve panics with this
message:

  panic: acpi: timer op not yet supported during boot

Could you help to check what happened here?  The full boot log can be
found here:

Thanks,

+29 September 2017. Summary of changes for version 20170929:
+
+
+1) ACPICA kernel-resident subsystem:
+
+Redesigned and implemented an improved ASL While() loop timeout 
+mechanism. This mechanism is used to prevent infinite loops in the kernel 
+AML interpreter caused by either non-responsive hardware or incorrect AML 
+code. The new implementation uses AcpiOsGetTimer instead of a simple 
+maximum loop count, and is thus more accurate and constant across 
+different machines. The default timeout is currently 30 seconds, but this 
+may be adjusted later.
+
+Renamed the ACPI_AML_INFINITE_LOOP exception to AE_AML_LOOP_TIMEOUT to 
+better reflect the new implementation of the loop timeout mechanism.
